After tinkering with different firmware versions for my ax210 vpro I got stuck with version 62.
I tried different approaches to activate newer firmwares but to no avail, reloading iwlwifi module or restarts didn’t help.
Then after a complete shutdown I powered the framework on again and to my suprise the firmware 67 got loaded.
It could have been by accident but this was my observation. Maybe it helps others.
