Find old BIOS or mod the BIOS? AMD Laptop MSI Alpha

[tea_time]

Hello everyone,

I own the MSI Alpha 15 (B5EEK-077) with the Ryzen 5 5600h and the RX 6600M. I am generally very happy with the notebook. Thanks to some settings, I am very happy with the performance in games (undervolting and overclocking the GPU).

I happened to notice that I am using an outdated BIOS. I updated it yesterday. Unfortunately, I discovered that almost everything is now blocked in the new BIOS. No undervolting, no overclocking, etc. The performance has been very limited since then. Unfortunately, I cannot find an older BIOS version. The version I am currently using is E158LAMS.10F. Since I cannot find an old BIOS version, I am actually considering whether the laptop's BIOS can be adjusted... unfortunately, I am a complete newbie. Can you possibly help me?

Kind regards
