How can I adjust the VAT for artwork sales on Shopify?

Hi,

I am selling artworks. The VAT is different for artwork than other goods. I live in the Netherlands and in the Netherlands it’s 9 %. My last work sold was sold in Belgium and in Belgium the VAT for an artwork is 6 %. However, Shopify is using the 21 % VAT.

How can I adjust?

Thank you in advance
