Can I apply for a Non-O Visa directly in Thailand without exiting the country?

Hi everyone! My non-B is expiring at the end of the month (my work permit was not renewed) I've planned to go to make a non-O (stay with child) in Lao next week as I've got all requirements fulfilled. Now, My flight might be canceled and the required quarantine in Vientiane won't help either. My question is; can I apply for the non-O directly here? Without exiting? Otherwise, the overstay seems inevitable :/ Thank you very much :)
