My dad gifted me a smartwatch(h1-c-aladeng) on my birthday, I very love it but I make a serious problem that I can't fix.

Its specification:

• Screen resolution is 240x240, very hard to read and type on a keyboard, and a slight misalignment of the touch screen.
• Running Android 9.0.
• The model(display in "Find My Device"): Lanix Ilium LT510

My problem:

• A lot of features have been turned off. That is why I use the developer option and turned some features back on, but I accidentally touched "simulate secondary display" and put a display on the screen, The "Simulate Screen" blocked the screen, and I can't reach the "none" option in the setting.
• During that time I have USB Debugging turned on and "always allow this computer" after that I accidentally turned the developer option off, I turned it right back on and I didn't know that action will clear all the authorized computers connected to it.

Before authorized cleared:

• I can still use ADB, recovery mode but it just shows "No Command" and auto restart.
• Boot to fastboot makes it put the "fastboot" on the screen after that it just auto restarts. I try anything I can't make it disappear.

I'm stuck with a second screen. and there is a way I can turn it off?

More:

• I think this watch doesn't have a real screen, it is likely this screen is just a small monitor like pc and has software simulate it because it has too much delay like I'm going to left It needs to be around 0.5 seconds to actually go into my point, It doesn't like a real phone have a mostly no delay. (I know that by installing Geometry Dash and trying)
• I have searched and there is a mode called EDL mode but I didn't know how to access it.
• I have an idea. I can connect to my phone using a micro to type c USB cable. Is there an app that can config the option of the OTG device?
• I am able to make the "Restore factory settings" tab pop up by pressing the button multiple time but I wasn't able to touch the "confirm" button:
• I stealthy my dad to open up my watch(don't worry my warranty is still there I didn't scratch anything) and here is the circuit in that:
