Waterproof question

Hi guys!
Can anyone recommend waterproof hardware that will run RealDash?
I ordered an Android device from China, but I realized it’s a bad idea because it takes 30 seconds to boot up, Android is limited, requires rooting, and the touchscreen is poor quality… overall, it sucks. The only good thing is that it has a separate ACC cable that turns on the device.(https://aliexpress.ru/item/1005009305059069.html?businessType=ProductDetail&sku_id=12000048682302356&spreadType=socialShare&srcSns=sns_More&utm_medium=sharing )
So, here’s my question: does anyone have experience creating waterproof screens based on a single-board computer, for example? Has anyone come across ready-made waterproof devices?
I’d be grateful for any advice.
