CloudFlare tunnel without Root Access

Hi, I’ve understood its possible to bypass CF by simply going to launch the attack on the origin server.
and one of the suggested solutions is a CF tunnel.
Now I’m hosting a wordpress site on SiteGround and they are fully managed which means I dont have much access server wise.
I’m not using the Shared hosting plans so I have a bit more freedom than others.

Is it possible and is it recommended in my case to set up the secure tunnel?
I’ve asked SG support and they said if its something that requires some root access it wont be possible, so does this secure tunnel requires something like this? or is it possible to do without any advanced server configurations
