How to "hide" some .py files into .exe with cx_Freeze?

Env:

Windows 10
python 3.6.6
cx-Freeze 5.0.2

Git hub example

It contails .msi for installing

Example project structure:

/package_name
        /some_packet
            /__init.py
            /module_name.py  # for an example contains valiable in code "module_1"
    /main.py
    /setup.py
    /some_module.py  # for an example contains valiable "module_2"
    /some_other_module.py  # for an example contains valiable "module_3"

Example of setup.py(simplified)

import cx_Freeze

cx_Freeze.setup(
    name="example",
    options={
        "build_exe": {
            "packages": ["asyncio"],
            "include_files": ["static\some_static_file.png"]
        },
        "bdist_msi": {
            "upgrade_code": "{492de237-1853-4599-a707-c283d567699f}"
        }
    },
    executables=[cx_Freeze.Executable("main.py")]
)

Current behavior

For creating .msi install file -> run command python setup.py bdist_msi. It will generate .msi files for installing application.

After installing this application: directory(where application is installed) will contain:

• main.exe
• lib\some_packet directory
• lib\some_packet\module_name.pyc file
• other files

There are following statements:

1) From root directory(where application is installed) i start search(via grep -Rna command under Ubuntu guest system, it's just more convenient for me) and valiable module_1 could be found in directories(in lib\some_packet\module_name.pyc) and module_2/module_3 couldn't be found.
Details:

(v_decompile) any@any-pc:/mnt/hgfs/shar/example_installed$ grep -Rna "module_1" 
lib/some_packet/module_name.pyc:2:B�!]�@dZdS)module_1N)r�rr�PG:\heroes\installer-with-cx_Freeze\sources_of_project\some_packet\module_name.py<module>s 
(v_decompile) any@any-pc:/mnt/hgfs/shar/example_installed$ grep -Rna -a "module_2" 
(v_decompile) any@any-pc:/mnt/hgfs/shar/example_installed$ grep -Rna -a "module_3"

2) File lib\some_packet\module_name.pyc could be easily converted to original file(without comments) by e.g. python-uncompyle6.
Details:

(v_decompile) any@any-pc:/mnt/hgfs/shar/example_installed$ uncompyle6 lib/some_packet/module_name.pyc 
# uncompyle6 version 3.3.3 
# Python bytecode 3.6 (3379) 
# Decompiled from: Python 3.6.6 (default, Jul 20 2018, 15:39:05) 
# [GCC 4.8.4] 
# Embedded file name: G:\heroes\installer-with-cx_Freeze\sources_of_project\some_packet\module_name.py 
# Compiled at: 2019-07-07 11:28:50 
module_1 = 'module_1' 
# okay decompiling lib/some_packet/module_name.pyc

3) (solved with this question) In both points: file contains source path G:\heroes\installer-with-cx_Freeze\sources_of_project\some_packet\module_name.py It confuses me a bit. Application was installed from .msi and (as I understand) should not know about source directories (regarding path) which was used for creating last one.

Questions:

1. Is there any way to recover some_module.py and some_other_module.py to original files from main.exe?(like it could be done with lib\some_packet\module_name.pyc)

2. How to "hide" some other files in application into main.exe or somehow avoid converting .pyc to original files.(maybe some properties in cx_Freeze?)

Note:

It should be done with cx_Freeze.

PS: I don't want to create single .exe. I try to find convenient way for specifying which files should be stored in main.exe like it was done with some_module.py and some_other_module.py

PSS: At this moment I see only I way: put all files on main.py level :) But it will look weird for big project.
