Hide Variations for Options that are not available

Hello,

How do I hide variations that are not available on the product page? You can see from the link below (https://customportraitshub.com/product/new-pet-illustration-portrait-combined) that it displays all the variations all the time, even after I select the first options. When I select number or animals on the portrait it offers 3 sizes there, even though only 2 sizes are available for portraits that are for 2 and 3 animals. All three sizes of portraits are available only for 1 animal portrait, for the other 2 types, I would like to see that option being disabled (or dissapear) right away when I click on the first variation. Right now when I click on this option it only displays the text “SORRY, NO PRODUCTS MATCHED YOUR SELECTION. PLEASE CHOOSE A DIFFERENT COMBINATION” in the end, which I do not want.

Hope I am making myself clear, thank you….
