Will this support my 9803dx

The product supports AMD Ryzen 7000 Series processors. However, a BIOS update may be required when used with a 9000 Series processor.

I don't want or need extra vulnerabilities in my PC. Anyway to get this or an equivalent without the wireless stuff?

What do you mean? Can you give an example of vulnerability?

does it support crossfire?

Yes, the MSI MEG X670E ACE motherboard supports AMD Multi-GPU, which includes CrossFire.
