    Welcome @MrBlamelt61122!

    Before attempting any type of modification (undervolt):

    Check that the UEFI firmware of your Nitro V15 ANV15-51 is updated with the latest available version (1.21 or above):

    https://www.acer.com/us-en/support/product-support/ANV15-51/downloads

    Because according to the changlog, there has been thermal optimization and also a CPU microcode update for these Nitro V15 models.

    There have been reports of users successfully using the Intel XTU and ThrottleStop, after disabling the Intel VTX option in the firmware settings:

    However, considering that your Nitro V15 was recently purchased. If your laptop's CPU is constantly maintaining high temperatures (close to 100 °C), there may be a problem with the cooling system.

    In this case, I recommend that you contact Acer Support and ask for your device to be repaired (RMA):

    Try to update the BIOS to the latest version and disable the Efficiency cores in the BIOS.

    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    Unfortunately, it is not guaranteed that you will be able to undervolt!

    Because depending on the UEFI / BIOS firmware used, these options may be blocked:

    Yet, you can also try disabling Virtualization-based Security (VBS):

    Unfortunately, I can't help you with this. Because approaches to firmware / BIOS modification tools aren't allowed here. 😉

    I still insist that you try to find a way to improve your laptop's temperatures in some other way:

    • Installing a base cooler;
    • Replacing the CPU and GPU thermal compound with a high-performance paste;
    • Or contacting Acer Support, to check that your laptop's cooling system isn't faulty.

    I wish you and family a Happy 2025! 🌟
