I was climbing to 31,000 feet, with the climb rate set to 1,500 fpm. Suddenly I got a red CAS message about cabin pressure and pressure differential. Where are the buttons to make the appropriate adjustments. Never got this warning before.

Yes, the cabin pressure differential can get into the warning range above 30.000 feet. It works well until 30.000 and with climb rates of up to 1.500 fpm. If you climb faster, the climb rate can also "outrun" the cabin pressurization (and lead to a pressure differential warning), which seems to be fixed at a maximum of 500 fpm.

Thanks!

Here is a tutorial I made on the TBM.  I cover every switch, panel, and most systems.  I have chapters setup so you can click the one around the middle for pressurization.  I show how it works and how it should work.  The COMPLETE TBM 930 Tutorial - Microsoft Flight Simulator - YouTube

Ricardo. You first asked "Where are the buttons to make the appropriate adjustments."  I did not see the answer to that in the video or in responses.  I have not flown the 930 so I do not know what the adjustability is or where it is (if any) for cabin pressure.  Each aircraft model has a limit of what value can be set for cabin pressure.   Here is the table I use for my pressurized GA aircraft.  The Cabin is expressed in thousands.  The aircraft is the indicated altitude (live altimeter setting up to 18,000, 29.92 altimeter setting above 18,000).

The aircrafts I fly that actually implement this are the RealAir Duke and Turbine Duke (both v2 for me).  Again, I do not know if the MSFS 930 models this.
 

Cabin	0.5	1	2	4	5	6	7	8	9	10	10.5
Aircraft	10.0	11.5	12.8	15.0	17.0	18.5	20.0	21.6	23.0	25.0	25.9

The table varies by aircraft model, so this is for the Duke.  In other aircraft that climb higher the table is adjusted to even out the gradations up to that aircraft's service ceiling.  I believe 10,500 cabin altitude is the maximum used.  So an aircraft with a service ceiling of FL430 the setting for that altitude would be 10.5.

Here is a great tutorial on the subject.  https://www.youtube.com/watch?v=-e_36SS6FU0

If i am not mistaken the pressurization in the TBM is fully automatic and can not be set manually to a specific rate.
