The code that needs to be patched basically looks like:
.text:00000000000B3E80 check_if_nvs4000?: ; CODE XREF: sub_B2B00+5C2�j
.text:00000000000B3E80 8B 45 00 mov eax, [rbp+0]
.text:00000000000B3E83 F6 C4 40 test ah, 40h
.text:00000000000B3E86 0F 84 45 F2 FF FF jz loc_B30D1 ; this is normally a jnz, we just change the 2nd byte (x85) with x84
