find the liquid that renders the tags filter, adding the data-value=“{{value}}” (value is the tag name/filter value)
and then in the CSS, create the display none for those tag that you want to hide
.facet-checkbox[data-value=“{{value}}”] {
display: none;
}
This is the easiest way.
Or you can try some filter app and exclude the filter option that you don’t want to show
