PC does not detect screen, keyboard, or mouse (secure boot)

Hello,
I've encountered a problem; I wanted to enable secure boot but at the moment I activated it, my PC turned off.
Since then, when I turn it back on, all the fans start, CPU and GPU,
but it no longer detects my screen, keyboard, and mouse, even though I've checked everything, like the HDMI cable and power supply, etc... I don't understand.
So the PC is unusable, no access.
I'm desperate, please help me ????????????????

Hello,
It's simple, you go back to the BIOS and disable your "Secure Boot."
... In the BIOS, not in Windows...
Hello.
When the computer starts up, Windows is not active. The drivers for the screen, mouse, and keyboard included in Windows are not active. However, the BIOS manages these three devices without any problem and without Windows. So, in the BIOS, you should have a display, a usable mouse, and a keyboard.
Best regards
The "b550 gaming x v2" motherboard boots into the BIOS... you can disconnect your hard drive for verification... You might not know which key takes you to the BIOS..??
If you have "no signal detected," it means the screen is functional... but it's not connected to the PC...
Windows BIOS doesn't exist!!! There is the BIOS... and there is Windows..
No, it's impossible, I don't have a screen, it's in (no signal detected) mode.
Even the keyboard and mouse are not detected
so I have no access to BIOS or Windows, really nothing
