I want to have the possibility to remote update the Firmware. The Current Firmware uses Tandem-Boot and that makes the PROM pins PERSIST. Can I use the Remote Update Functionality in this case?

I guess you are talking about update PROM stage 1 image by PCIe link? Or you are talking about Tandem PCIe with Field update?
If the former, you need to use Tandem PCIe instead of Tandem PROM.

What is the reason for the persist configuration requirement in Tandem PROM? Why does the FPGA need to keep those lines blocked? Is there any traffic occurring on those lines after configuration?
Would the following work? : Multiplex some other FPGA IO pins against the FPGA configuration pins externally via a multiplexer on the PCB and thus regain access to the flash from the FPGA user design?
