You are wrong in both aspects
The first LHR version is a lock inside the drivers, wich can be unlocked using NVidia driver 460.39 or lower.
The second version of LHR is a bit different, they started releasing them in june '21 and if you try to use those cards with driver version 460.39 or lower, the system doesen’t detect the cards, so you have to use higher than that, thus triggering LHR.
taken from a reddit post:
I see some confusion between both variant so I made this post. The infos come from various distributors, MFG representatives and so on…that I talked with. This info only applicable to 3060-3080. 3060Ti/3070Ti/3080Ti are already LHR card. 3090 will not get LHR variant.
+Gigabyte: LHR card will have REV 2.0/REV 3.0 text printed on the sticker, both on the box and card. FHR card do not have those text.
+EVGA: P/N of LHR card end with “-KL”. For FHR card it is “-KR”.
+Asus: REV 2.0 text on the box and card stickers for LHR. No Rev 2.0 text for FHR.
+MSI: currently there is no way to tell beside testing the card with internal software or ask the distributors, they get advanced info from MSI which batch is LHR. One unofficial way is to look at MFG year/month (13th-16th number in serial number, like “2106”) and check, 2106 and later has a high chance of LHR card.
+Colorful: series or P/N end with “L” for LHR. FHR card is “V”.
Also for all MFGs you can look at MFG month, all MFGs started production of LHR in Week 2, June 2021 while Asus started a week later, Week 3 June 2021. But this method is not exact
