OK, so I don't recommend this often, but there is a FOSS option closer to Nova than Lawnchair. It's called Neo Launcher: https://github.com/neoapplications/neo-launcher

It may be worth a shot, I ran the release on GitHub for about a year. I stopped because the devs are doing this brainrot thing of putting releases as beta in their Discord, so the release file on GitHub is old. I hate that practice so much that I stopped recommending it, even though it's a slightly better launcher with more options IMO.
