How can I terminate my F-1 status if I have pending EB-5 receipts?

Technically yes, as you are in a period of stay authorized by the Attorney General, but the most conservative position is to maintain nonimmigrant status (F-1 or otherwise) until your permanent residency is actually granted. Up to you.

A properly filed I-485 will allow you to remain in the US without accruing unlawful presence, even if your previous F-1 lawful status terminates. This is a period of authorized stay, which is less formal and less robust than a lawful status, such as F-1. Once you receive your I-131 Advance Parole, you can also leave and reenter the U.S. and once you receive your I-765, you may accept lawful employment regardless of relevance to your studies. One risk worth noting is: if anything goes wrong with the I-485 adjudication and it is denied, then the period of authorized stay will end. If you do not have another lawful status to support you, then you will begin to accrue unlawful presence. Some F-1 students prefer to keep their F-1 status for this reason, even with an EB-5 I-485 pending. It is recommended to consult with an experienced immigration attorney for advice specific to your circumstances and plans.

Yes, you can do that and still be allowed to remain in the U.S. assuming you were eligible to file for adjustment.
