Are you 100% sure it is a swap file? If so, I would simply try:
$ sudo rm /dev/zram0

Have you created this swap file yourself? I do not have it on my system and an application would need root privileges to create something in /dev.

I have it on my 5.5.

Perhaps you could define a higher priority in fstab for the regular swap (see man swapon).

Good! If you wish to get rid of zram for good, put these commands into some late startup script (run as root)

swapoff /dev/zram0
modprobe -r zram

The first command stops using it as swap and the second removes the module.
