Wix Store - Set option availability

Hi,
I’d like to control by code on the visible options of a product.

For example, let’s assume the product is a T-Shirt with a Size option (M,L) and a Color option (Black, White), hence there are 4 permutations:

  1. M-Black
  2. M-White
  3. L-Black
    4.L-White

I’d like by code on Mondays only to hide the ‘Black’ options and have only the ‘White’ options visible: M-White and L-White.
I thought about having a back-end wix store code that on Mondays remove the ‘Black’ options from the product’s available choices or options.

Is it possible with the wix store Code? If so, I’d be happy for some help and directions.

Thanks,
