The closest I've been able to get is to buy a Protectli box, replace the AMI with Coreboot that you can compile yourself, and install OPN/PFSense.
It's still Chinese hardware, but it's warrantied by Protectcli and you have control over the bits you can change.
My first move out of the consumer "junk" was Ubiquiti EdgeRouters but their software quality declined a few years back, and my models got no more updates, then my main router died. My overkill i3 6-port Protectcli box has been running great ever since; first with pfSense now OPNSense; I'll only replace it when it dies or I want 10GbE routing.
