You may already know this, but gufw is simply a graphical front-end to the Uncomplicated Firewall (ufw) service. Fedora uses the Firewalld back-end service instead of ufw.

Why do you think Gufw is proprietary? It's FOSS, licensed as GPL v3, as documented here. Source: almost 3 years ago
Another option is to use UFW and rate limit incoming packets. Because it's a firewall, it will block the queries even before they hit Pi-hole, but it might be a tad more tricky to set up. I also don't know if you can set it as a limitation per client or only in general (per port/rule). I'll leave that for you to investigate further. Source: about 3 years ago
