I really need a help to rotate the screen properly

[/RaspberryPi]

After do a fresh install in my PI4 B, I installed the Waveshare driver to my 5inch screen (https://www.waveshare.com/wiki/5inch_HDMI_LCD)

But when I was trying to simply rotate it (it was upside-down), absolutely none worked.

The only thing "semi worked" was put this into /boot/cmdline.txt:

video=HDMI-1:800x640M@60,rotate=180 But the case is when my PI4 B starts (its used in a 3D printer) the screen show the console upside-down... and when the KlipperScreen starts, it fix the rotation.

Could somebody help me please?
I expend the entire day reading and try to learn what's happened but looks my case is totally different from the others fixed with "rotate_display" properties into the /boot/config.txt
