Your choices include

Change your minimum via diameter to 0.2 mm. Once you have 4 or 8 0.2-mm vias in your design, adding more won't change your cost much.

Add these vias to a class, and make a special rule for that class with a 0.2 mm minimum diameter.

Increase the via size to 0.3 mm, with some risk of solder wicking through them and starving the thermal pad connection of solder.

Ignore the errors.
