Sorry to hear never good when things are not working. once you try the GPU in another computer you will no for sure. Really sad to hear such a high end product having a failure. 

Tried it in another PC at a friends house, no dice.  Same red LED in the same position.  Got an ASUS 4080 for now.

It has been years since EVGA offered a repair service, and there are basically no new products for you to purchase from EVGA, so I don't think EVGA will feel the boycott.
 
EVGA's 3090 cards were a disaster.  Too cheap of hardware, pushed too far.

You can try someone like Northridge fix (or other similar ones), but this was usually a VRM failure and even if you can repair it, it'd likely happen again because the original card design had a bad controller topology that allowed surges that can eventually kill the card. There are a number of design problems with all 3090's that I think will cause them all to die if ran long enough, but EVGA's early 3090's had some extra problems (that were fully allowed and supported by Nvidia, by the way). They eventually rev'd the cards to put in a better VRM controller (the 3080ti, being launched later, also benefited from a better design), but the "Rev 0.1" ones are quite susceptible to early failures.
