Can someone switch from a Non-O volunteer visa to a Non-O teacher visa while in Thailand?

Edit:

Saw that the COVID extensions and some of the convenience factors of visa renewals were rolled back, so question answered: visa run required.

Have a friend of mine that is transitioning from an existing Non-O (volunteer) to another non-o (teacher) and told she has to switch to tourist first.

Are they not allowing this done in-country anymore? It’s been a minute since I checked the latest and greatest from the great ‘Taw Maw’.

Thanks!
