You should read the existing P3222QE threads on the Apple Forum. If need be, start a new thread out there stating the issue to get possible assistance from other macOS users.
* Disconnect every cable (including power cable) from the P3222QE
* Press the P3222QE power button for 8 seconds
* Reconnect ONLY the power cable to the P3222QE
* Run the Built-in Diagnostics (page 70 in the online P3222QE User's Guide)
- If you see the backlight flicker during the Built-in Diagnostics, the P3222QE is faulty
- If you do not see the backlight flicker during the Built-in Diagnostics, the P3222QE is OK. The fault is either the cabling or the macOS or its drivers.

Thank you for your contact
I tried as you mention on Built-in Diagnostics and Windows is ok but on Macbook Pro 14" still have backlight flicker problem and It occur more frequently when gray background on screen as you can see on video earlier post https://youtu.be/Oft6FHGTUYk
Both connection USB-C to USB-C and HDMI to HDMI still have backlight flicker problem
