HP ProDesk 400 G5 SFF BIOS 4G decode & REBAR enable

[iulik17d]

Hello everyone!
I've paired an Intel Arc A380 with this PC but the performance is not so good because the bios don't have 4G decode and Resizable BAR enabled.
With an CH341a I extracted the .bin file from the 25Q128 SPI memory. Can someone work some magic on that .bin file to enable or add the 4G decode and REBAR to it?
The model number is: 2ZX70AV
Thank you!

Hello again!
I'm trying to add rebar FFS module like in this tutorial https://github.com/xCuri0/ReBarUEFI/...ing-FFS-module but I can't find list of modules DXE Driver. I found some information on the internet to put the FFS in the biggest volume availabe, in my case that volume contains a lot of PEI Modules. I inserted the rebar FFS module, saved modified .bin file but the Uefitool freezes when i want to open the modified file. I tried flashing the bin file anyway but the PC don't want to power, it beeps.
I tried insert the module in some others volumes, i have luck when inserted in the folowing volume, the PC boots but the rebar is not active after using the ReBarState.exe for settings and check status.

In what volume i should add the FSS rebar module?
Thanks!
