Maybe the 3070 lacks of VBIOS to support Rebar.  The firmware was available at one point then it was pulled.  See the comments at this thread https://www.dell.com/community/en/conversations/alienware-desktops/enable-nvidia-resizable-bar-for-rtx-3080-3090-3070-for-aurora-r10-r11-r12/647f93c2f4ccf8a8de5e7ebd?page=1

If it's an OEM 3070 to my understanding they never released a VBIOS to update the card to include REBAR. Besides motherboard BIOS support you also need VBIOS support.

This is the latest available BIOS update for the 3000 series cards: 3000 series VBIOS

If you have that one already, and you have no REBAR, than the VBIOS does not support REBAR on the 3070.

If you don't have that VBIOS but an older one, you can flash your video card with it but be very careful as there's no recovery option available should the flash fail.
