Setting up Cake on a Fixed Wireless Internet Type

[Zachattack9399]

Hello everyone, I am new to the community (and networking) but have been searching for what to set my WAN packet overhead for Cake. My current router is the RT-AX86U Pro. I am trying to find which setting to use (Ex: PPPoE VDSL or VDSL PPPoE PTM.) My internet uses fixed wireless (line of sight) technology. I'm unsure what information to provide, but we do use PPPoE to connect to our ISP. Thank you for your time and effort.

I should add that my ISP won't escalate my ticket so I'm having difficulty finding the needed information.
