What type of home assistant installation are you running? It seems to be not possible on hass os. The error means fuse is not installed on the host but ha os dont allow you to install it. Your best option is to switch to home assistants supervised its home assistant with debian 11 as operating system instead of hass os. Here is a post of someone that installed fuse on hass os but is seems not to be working and lost at reboot Install FUSE on Home Assistant OS . But im running plex with 2 google drive storages mounted to it but i use home assistant supervised on debian 11 in that way you have more control over the OS. To install supervised follow this tutorial Installing Home Assistant Supervised on Debian 11
When you install stuff on the os you may get ha unsupported but that no real issue only installing rclone wont make it unsupported for now but this may change in the futher. Im running this for over a year even updated from debian 10 to 11 without any issues. You need to add some tweaks to the rclone config for performance upgrade. I can look up those tweaks for u that i used wen you get there. You could also google plex with rclone many people use this.
