Any BIOS for the Inspiron 5400 2 in 1 that allows undervolting?

Attention BIOS experts! I’m looking for your help!

I have an i5 1035G1 CPU in my laptop, the Inspiron 5400 2 in 1, and I’m looking to safely undervolt it using a modified or old BIOS that allows undervolting. I am using Throttlestop to do so.

If you have experience modifying laptop BIOSes and know how to undervolt this specific CPU/Laptop model, please reply!

Thank you in advance for your help.
