That won't make any difference.

The support for accelerated graphics isn't upstream yet. There's a few
series of patches that would need to land, at least this one [1], and
one to support HDMI, possibly more. Looking at [1] I doubt that will
now land for 6.8, the rule of thumb is usually it has to be accepted
by rc5 of the previous cycle, so we'd be looking at 6.9 at the
earliest assuming any other patch series also land, it'll also need
patches for device tree. You could collect the patch series together
and build a kernel if you want it before then.

You need to put the FW on the SPI flash, not sure if the firmware
supports that yet, but there's confirmation it'll work at some point
in their FAQ:
