bypass "X-Wap-Profile"

[adhk 0]

Hello everybody!  1st. thank the "airvpn" for their Useful & Educational pages! 
 ★Q: Sometimes after changing "User Agent"of my browsers (on Mobile), some sites do not open, even if the UA string is set correctly, Example; "wordpress", "Twitter", etc. I think it's due to"X-Wap-Profile" query (as in "ipleak.net"). Most websites use this method. How can i find if a website performs this method? And is it possible to block it?  Example: most of UAs working on my Firefox, doesn't work on "Monocles" browser, also "WebRTC" on both is Disabled & the UA string is same and "Android System WebView" on my Device is Disabled. If the "X-Wap-Profile" is part of the "HTTP HEADER" , is it possible to set up the browser to not send this part in the Header?
