Can I ask why you would want to separate VFR vs. IFR avionics checks? I like
to include any IFR avionics pre-takeoff checks in my standard checklist so I
check them during VFR flights as well. I like to know if *anything*
regarding avionics is not operational. Plus, there are only a few
IFR-specific checks:

For VFR flight, the avionics are non-essential. I can fly without
turning on the avionics master, leaving everything off. The only thing
I need to depart or land at a controlled field is a COMM radio. (I can
get an exemption for not having other equipment for CBAS.)

If it is turned on and something goes TU, it doesn't matter (unless you
are flying into an area of changing or marginal weather where you
anticipate converting from VFR to IFR).

For IFR flight, I intend to use all the equipment, so I run through all
the avionics preflights. If the autopilot isn't working and am flying
single-pilot, that may be a go/no go item. Same for any other avionics
item. If it isn't working and it's deemed essential, decisions must be
made before launch.
