"AMI" screen following motherboard change on Windows computer

Following a change of motherboard after twisting pins of the processor socket, I bought the same one.
 
Everything is reconnected, it starts, and I come across a new screen on a black background "AMI" which asks me to do "Y" or "N".
 
By doing "N", Windows starts, the problem is that each time I start I have this screen which tells me that I have built a new CPU.
 
I made all the motherboard updates.
 
I hesitate to make the choice "Y" which talks about bitlocker (not activated on any of my hard drives). Does this tell me about fTpm...?
 
Thank you for your guidance!
 
Ps: my microsoft account tells me that I have not generated any bitlocker recovery keys.
