Windows 10: I got black screen after disable csm to enable secure boot

I am using a B450M-HDV R4.0 mainboard from Asrock, I want to enable secureboot for my game Valorant because without it I cannot enter the game, but when entering the bios, to enable secure boot I need to disable CSM, but when I save and reload to enter the bios again and enable secure boot, my screen is black, there is no signal at all. I have tried switching cables like HDMI, Display Port but it did not work, I also tried updating the BIOS but it still did not work. What should I do now, I hope everyone can help! Thank you! I am using ryzen 5 3500 B450M-HDV RS4.0 from Asrock and 8gb ram RX580

Cannot disable CSM to enable Secure Boot

Winver. 22H2 19045.3208 Hi there, I am having difficulty in enabling Secure Boot even when it is supported with my motherboard on the ASUS website. I was made aware of this by using the PC Health app:

After a bit of research, CSM being enabled in the BIOS can be a reason why Secure Boot is showing up as Unsupported on my msinfo32 report:

However, I cannot disable CSM on my pc as it does not boot Windows 10 after the change, meaning that either something in my pc does not have a UEFI driver or that it is due to my primary disk being MBR and not GPT (according to research). Any help with potential fixes or suggestions is much appreciated, thank you
