The recurrence patterns in ADF and Logic Apps don't directly support this combination of requirements. You are certainly welcome to attempt this in an ADF pipeline, but I find Logic Apps to be much easier for this sort of action. Below is an example of how you might configure it:
Create a Logic App with a Recurrence Trigger
In the Trigger, change the Frequency to Day and specify the hours and timezone:

Calculate the day of the week
Us the following expression (change to the appropriate timezone) to extract the day of the week into a variable:
dayOfWeek(convertFromUtc(utcNow(), 'Eastern Standard Time'))
This will return an integer where 0 = Sunday, 1 = Monday, etc.

Add condition based on the day of the week
Use the dayOfWeek integer variable to determine which days to act (or ignore). In this example, I'm exceluding days 0 (Sunday) and 6 (Saturday):

Execute the data factory
In the True condition, execute your data factory (do nothing in the False condition):
