nope based on Thai child, parents of foreign children can get a guardian visa if their child goes to international school, 1 visa per child. Seasoning is required and it's 500k on the bank. For a foreign parent of a Thai child the visa is similar but it's 400k in the bank on day of application only. That is for male foreign parent, I believe that if it's a female foreign parent of a Thai child there is no financial requirement
