Can I extend my standard tourist visa for 90 days in Thailand without leaving the country?

You can get a multi-entry Tourist Visa from your home country so that you don't have to apply in a neighbouring country and wait for up to 3 days. Only one border bounce to get up to 6 months in Thailand.

if you only want to make one trip out of Thailand, expect to spend at least 2 days at a Thai embassy in a neighboring country as you'd need to apply for another tourist visa and none of the nearby embassies offer same day service. Some are drop off one day pick up the next business day, and some are 2-3 business days later.

If you just do a border bounce where you leave and immediately return, you'll only receive visa exempt which is 30 days and can do 30 day extension, meaning you'd have to do this twice to hit 6 months.

the standard tourist visa gives you 60 days which can be extended by 30 days at your local immigration office. Then you need to leave the country. If you want another standard tourist visa you have to visit a Thai embassy in a nearby country which takes time. Or you can just leave, stamp into another country and return which will give you 30 days visa exempt, this can also be extended for 30 days
