Describe your question.

How am I able to remotely turn off the lidar when I'm not using it. When using it remotely it'd be convenient to not have to unplug it every time.

Hi there,

The Create 3 robot does not ship with a LIDAR. Perhaps you have a derivative product, like Clearpath's Turtlebot 4? If so, you might find an answer here.

A lot of LiDARS just spin by default if they're plugged in - for example, the RPLidar! My solution is to leave it unplugged unless im currently using it.

First you need to review the API for your particular lidar. There is likely a lidar.stop() function that can be called by your software.
BUT, second you have to modify your particular ROS2 lidar driver to stop publishing the /scan topic when the lidar is stopped. If you don't do this, the ROS2 lidar driver will likely throw an exception or at the very least send invalid scan topics.

As others have stated - the Create3 does not ship with a LIDAR, so perhaps ask on the forum that supports your LIDAR.
