It can’t unfortunately - Athom is using legacy Raspberry Kernel Linux version 6.1.21-v8+, which is not compatible with CM5 (actually maybe it is, but it would be un-stable/un-tested/not recommended) and is using old GPIO approach. With the announcements of OTA updates, I’m not sure if they will be switching kernel at this moment…
You can read more on :
More over, new LTS Kernel will be 6.18 - so it would make sense from Athom to move to this Kernel version, which require :
-
switching from SYSFS to the libgpiod
-
required OS dependent changes, starting scripts, GPIO assignments etc.
-
required homey-pro container adjustments to the GPIO changes
-
and many additional changes…

I was able to switch to the new Kernel already before but GPIO related actions were not working as it should - eg. reset button, Wifi setup etc… I gave up, the best and smoothest way is currently to use simply CM4108032 (extended space available only after repartition) or CM4108016 (same as 32 - repartition required) or CM4108008.
