Hi,
I have read docs at https://openwrt.org/docs/techref/hardware/soc/soc.broadcom.bcm47xx and tried to install 24.10.3 trx image `openwrt-24.10.3-bcm47xx-mips74k-standard-squashfs.tr
Im currently hitting dead end because of trx magic mismatch

I have found some patches from 10+ years ago on google. This means that someone must have installed it successfully (old builds with kernel 3.x).
There is also this forum post Please update wiki for F7D3302 v1
and Are Belkin F7D routers supported in LEDE? - #10 by tmomas
I guess that router is not supported officially but in theory openwrt SHOULD run if it can be installed in first place.
