S7103GM2NR not working resize bar ((

[shpinog]

I flashed my "S7103GM2NR" and added the FFS module. I decided not to apply "UEFIPatch" since the motherboard has a 4G decoding setting and boots normally with it. I couldn't flash the BIOS using afu, but it worked through IPMI.

Next, I get:

lspci -s 1a:00.0 -vv | grep -A 10 "Resizable BAR"

But when checking dmesg output, I don't see that it's enabled. What could be the reason?
