New CoreBook X i9-13900HK CP tuning questions

Hello.
I have a few questions about the upcoming CoreBook X. Will the BIOS be unlocked, and will Intel XTU be supported? Certain settings in the BIOS can disable undervolting, and since the 13900HK is an unlocked CPU, undervolting is possible. I had good experiences with unlocked desktop and laptop Intel 13th gen CPUs, where undervolting can extend battery life, lower the CPU temperature, prolong boosting etc (so more performance…). A lot of benefits.

And my biggest question is: Any plans to bring the 7840HS to the CoreBook X? A better allrounder with better battery life and 2x the graphics performance in comparison to the 13900HK.
