PS. Make sure you do it when the tires are cold (aka not after a drive). Those should be cold tire PSI. They will go up on driving, but you want them to be 30/32 when cold.
will do. Will the display be correct or have "-1" etc?

Here is what you do to tell the PCM which Tire Pressures you are running.

FWIW, on the 2022 with PCM 6.0. they've changed the description for the checkbox from Comfort pressure to Partial load.

FWIW, the comfort pressure setting not only have a slight improvement in terms of comfort, but also have a big impact on noise over rough surfaces. One of the roads I frequently drive is brick (not exactly cobblestone, but very rough) - it isn't harsh in terms of jolts/roughness, but is super loud with standard pressures (which the dealer seems to reset to no matter whether I ask them to keep it in comfort settings). In comfort, still loud, but noticeably improved (great, now I can clearly hear my wife nag). Off topic - reminds me of that classic 911TT add - 'gets a little louder after 5,000 rpm so you can't hear the passenger scream.'
