Hi,
I don't have this problem on my 2 trinket modded Switch, but it reminds me the problem I had with my Switch Lite (modded with SX Lite, reflashed with spacecraft-nx).
Don't know if it can help, but I had to change autohosoff=0 to autohosoff=2 in hekate_ipl.ini. Then, when I power off my Lite, its screen turns black, but Switch is still "alive", and I have to wait ~20 sec until it shutdown properly (SX Lite Led briefly blinks green/red). If I remove the microSD before SX Lite blinks, after shutdown, It says "SD CARD" with the spacecraft's screen. If I keep autohosoff=0, then the Switch restarts by itself.
But with a trinket m0, it should power off directly (does on mine...I made the full installation, all wires, "official" points). Really weird.
autohosoff=2 could help (even if it bypasses the problem instead of correcting it)
From the github :
- xboxexpert has reported that sometimes the trinket will wake itself up ~10 to 13 seconds after a poweroff. The trinket quickly goes back to sleep and this seems to only happen once per poweroff and does not continually drain the switch battery. I cannot confirm because I do not want to open my switch again and the light is not visible from the outside.

EDIT : it seems to be related to autoRCM, check
