There is a nose wheel lock located on the front of the stick. Locked/Low/High settings. I’m trying to find a way to bind it to something for easier use. If you can’t locate it, go to checklists -Nose wheel lock / before take off and click on the eye on the right side of the check list item. It should pan right to it.
It’s also mentioned here as an alternate method using buttons or keys binding, as also reported through the link @longhaulsky provided. This is an addition to the axis way.
