They need to figure it a different way to do enforcement that’s not as discriminatory. The current approach leads to disparate outcomes and is therefore inherently discriminatory
For example, if you have 2 groups of people and one of the groups is doing something wrong twice as much, and you enforce the law on everyone... it's fair, not discriminatory. (Ignoring the fact that what is labelled "wrong" can be done in such a way as to be discriminatory. I'm assuming a neutral view of what is wrong )
