I have been thinking about getting the ZenFone 10 as well. I have seen a lot of similar posts here and on various google searches. In the XDA forum for the phone there also a topic about not being able to unlock the bootloader/root, but there is a bit more info on the reasoning.

“A moderator in the Asus ZenTalk forum posted that they are working on a new release of the unlock tool and that it should be available in Q3 2023.”

It really is beautiful there! You would also want to go in late summer as the snow tends to stick around at that elevation. This was taken the first week of August a few years ago and the snow is mostly gone.
