Need some inputs

Hi I just ordered Ag02 and will use it with my ROG Ally X. Since I have spare rtx 2070 I will use it to this setup. So any tips or inputs that I might need when setting this up? Is it plug and play?
-I do have a Gaming desktop but since I work overseas and travelling most of the time that’s why I opt for Handheld+Egpu.
Looking forward to hear from you guys
