New Linksys AX5400 router compatabilities

I just received a new router from someone. It is a Linksys AX5400 E9450. Is anyone aware of anybody else that is attempting to install any of the 3rd party firmwares on this router? I really want to run 3rd party firmware and got this router for free. I'm hoping to run Openwrt or some other firmware without having to buy another router since I already have this one.

(for some reason wikidev showed me the wrong device)

Broadcom, I wouldn't get my hopes up.
