As far as I know only Lolminer at first did that but it is not 100% unlock,it is still 74% unlock at maximum but it gives you somewhat better payouts as you are mining two coins at the same time.I do not know any 100% LHR unlock yet from any miner except from the scammers which tricks you into downloading just malware and not the real miner.
Lolminer was not the first by the way and he speak about the dual mining mode from t-rex miner for mining eth+alph, such mode is not available in lolminer
yes you can mine eth+alph with t-rex miner. I use for my 3070´s 1350 core, 8200 mem and 740mv for the gpu -> 42mh on eth and around 350mh on alph.
Any CUDA application that fools the LHR detector will work, but you don't want it to compete
for GPU resources with the primary mining algo.
It's presumed LHR is fully disabled but full performance may not be achieved on the primary algo
due to competition from the decoy process.
But a dual miner is easier to use for most of the people.
