In reality the 90 day report would be done online or via mail to office where you usually live.
No need to file a TM30 and do your 90 report at a province just because you are staying there .
For example in March 2020 I stayed on Koh Samed for 8 months, due to covid restrictions in Bangkok and elsewhere.
I did my 90 day reports via mail to CW as that's where I live.
