Can I quarantine in Chiang Mai after returning from the UK, or do I have to do it in Bangkok?

Hi. I am flying to the UK from Chiang Mai this month returning in November. Chiang Mai has a ASQ hotel but I cannot find any information as to whether or not I can fly back t Chiang Mai to quarantine or if I have to do my 10 days in Bangkok (no direct flights to Chiang Mai). I have searched all the obvious resources and still do not have an answer. The hotel itself does not know since the full details of the changes have not been sent out to them yet. I thinking this means I can't but thought I'd check to see if any one knows anything :)
