OC (MLo-> OCLP)

Have an open core 0.6.3 big Sur running massive Mac Pro 5,1 with every single upgrade you can imagine, big Sur is running on the internal x4 nvme 2.0 PCI E slot card but I have SSD‘s in the optical drive bays (apple raid as scratch) and spinning platters also and Possibly room to add a secondary nvme 2 PCIe drive, is there a way to non-destructively tryout OCLP sequoia on this machine? I have done this on a MacBook 2015 and it works very well I just don’t want to destroy firmware and the graphics card et cetera or stuff up the NVRAM et cetera on the back plane and break this beautiful behemoth Thnx
