Disabling Reed Solomon

I’m trying to come up with my own encoding/decoding scheme. So, I need to disable CRC check (FCE), RS error (RSDE), and any PHY errors (PHE).
I’m aware of DIS_FCE, DIS_PHE, and DIS_RSDE bits and also the possibility to disable adding CRC on the packet, but I’m not sure what behavior I should expect on the receiver side when these errors occur.
See my other question: Reception behavior when enabling DIS_FCE, DIS_PHE, and DIS_RSDE

Can I still read the corrupt data from the memory? and how?
