Limit variant keys

Hi,
How can we limit the amount of options people have to pick ?
For example:
with the product “losse stickers” there are a bunch of option people need to pick that only have one option. For every time they pick that option it needs to load and makes the whole experience very slow while we already know they can only pick those options.
We’d like to limit the amount of options, how does it work ?
