Can I install Android P Beta to my Galaxy S8? I want to install Android P Beta to my Galaxy S8 device but after I went to https://www.google.com/android/beta I can see that only Pixel 2 device can opt out for an upgrade.

Is it ok if I opt out for the Pixel version or this will be dangerous for my device?
It would be disastrous to do that !


As you mentioned it is only for Pixel device and flashing it on your device is same as asked here Can I install a ROM made for a different device?
Your device doesn't have treble 
support as mentioned here and you are wanting to flash a treble based ROM, which requires major changes to be done by developers


Unless you fancy an expensive paper weight , don't
