Dear @Whillie18,
thank you for sharing your question with the Wefugees Community.
Based on section 60d of the Residence Act of Germany, one of the requirements for a Beschäftigungsduldung is that the person should have entered Germany before 01.08.2018, and your father, unfortunately, does not complete this requirement and is, therefore, not eligible for it.
If you have further questions, you may go to my profile and read the description how you can get in touch with me directly.
Best wishes
Fardeen Noori
