Can I change my Non-O visa to a B visa while in Thailand or do I have to travel abroad?

Hi everyone. Long story short, I am on a student's spouse visa (O visa for relatives of foreigner students in Thailand). I got a job offer from a BOI company but to be able to process the work permit, seems I have to change my visa to an other type visa that is eligible for work (B type). Any way to do this directly inside the country ? Company says not possible within Thailand. Feel the pain having to travel and apply at an embassy outside, with all travel restrictions in place, quarantaine etc... Thanks ya all !
