Gravel Kings 700 x 43c tyres on Cannondale Topstone RX

I am looking to max out the tyre width for my Cannondale Topstone. It currently has the stock WTB Riddler 37cs with plenty of room. I'm also aware that Cannondale Topstone have an advertised max tyre width of 40c though they also say that this has loads of additional clearance. But I am always curious if anyone has tried pushing this to 43c on the Topstone without any issue?
