Victus by HP 16.1 inch Gaming Laptop PC 16-d1 (53F54AV)

I have a laptop that is in GPT mode and i want to change it to MBR mode, i tried doing it by holding shift and restarting then opening my cmd, and converting it. After that finished i tried to boot back into windows and i get (Boot device not found) so i was wondering how can i switch to mbr from gpt. I fixed the boot by just reinstalling but i need help converting. In the newer hp bios i can disable secure boot but theres no legacy mode option anymore. Thank you

even with no boot, i tried to install a mbr windows 10 22h2 file and i couldnt install it, it wasnt even detected while a gpt one is. I need to enable CSM but i dont know how to do that

I just tried the same windows 10 mbr file on my old laptop and it worked but on my new laptop it dosent, i enabled secure boot tried to disable it, reset bios setting. I think its to do with my laptop hard drive not supporting mbr but i dont think thats a thing
