You can edit the entry and set the “matching rule” to “Never”. That will effectively “hide” the item from appearing in any autofill selection listing.
Another practice is to prefix the name with “z” (lower-case “Z”). One would think that the highest ASCII printable character, “~” would always push items to the bottom of any list, but one would be mistaken. In BitWarden, the opposite occurs, and they appear at the top of the list!
I also create a folder with the name “zzArchive” and move those entries into that folder for an extra way of separating them.
