How to only show context without nav?

[23WilliamDing]

I wanna ask for help: how to only show context without the left nav?
This is because sometimes I need to show the left nav, but sometimes I don't need to. Could I realize this by using a parameter in url? Just like, https://docs.requarks.io/install/requirements?showNav=true or https://docs.requarks.io/install/requirements?showNav=false.
@NGPixel any suggestions? THX!

That's not possible no.

Thank you for your response. I find a solution on my own :
I inject javascript to identify url, then if it includes 'showNav=false', I use css to hide nav, it works.
