Disable showing of one option in variants

[pikastore]

Hi, ive encountered an issue with variant selector on my shopify website with dawn theme (my website - pikastore.cz). I want to hide the variants where is only one  option to pick, so it looks more clean.
Thanks for your help in advance

Hi @pikastore,

What theme do you use? You need to edit code file liquid such as: product-variant.liquid. I think you should let developer do it.

The theme I am currently using is "Dawn". 
I believe I can resolve the issue on my own, but I need correct code so I can insert it to my theme.liquid.
