Dynamically change VAT rate on checkout

From new year in January we will have new VAT rate for solar panels but with small rules: for business clients rate will be 19% but for private clients 0%.
So is it possible on Shopware use condition when customer = commercial then use 19% rate else 0%?

Sure, just change the rate in the customer group.

I see only visual setting in customer group: show NET or GROSS VAT
Where I can change what you mentioned?
