This is example how you can do two of three fields make readonly in admin panel.

models.py:

class Demo(models.Model):
    example_field_1 = models.CharField(max_length=1000)
    example_field_2 = models.CharField(max_length=1000)
    example_field_3 = models.CharField(max_length=1000)
    
    def __str__(self):
        return str(self.pk)

In admin.py:

from django.contrib import admin
from . models import Demo

@admin.register(Demo)
class DemoAdmin(admin.ModelAdmin):
    readonly_fields = ['example_field_1', 'example_field_2']
