Limiting taxonomies in search form

Is there a way to limit the taxonomies that show up in a search form, based on their parent taxonomy? I’m building a site with a clothing directory and have different search forms for Men’s and Women’s clothing (Men and Women are custom post type categories), along with separate sub-categories for each.

I’ve been able to limit the results from each form using the code supplied here: https://support.searchandfilter.com/forums/topic/limiting-search-results-to-a-specific-category/. I’d really like a way to limit the taxonomy terms that appear on the search form without having to individually add the terms to exclude each one, as it will be upwards of 30-40 terms to exclude.
