Can my wife volunteer for charities in Thailand on a DTV visa?

Volunteering while on a DTV (Digital Nomad Visa) in Thailand is generally prohibited unless you have a proper volunteer visa and work permit. Multiple comments emphasize that volunteering is considered work and, therefore, requires a work permit, which cannot be obtained on a DTV. Some users mention that while technically it's forbidden, many people volunteer informally without issues, particularly at well-established organizations. However, this practice is risky and may attract scrutiny from immigration authorities.
