Can JMeter support HTTP method CONNECT

Question

HTTP method CONNECT is part of available HTTP methods,

In Fiddler HTTP CONNECT is also saved and can be export to HAR format and then converted to JMeter script,

In JMeter those HTTP Request are failing,for example request CONNECT http://graph.facebook.com:443/

With the following error:

org.apache.http.client.ClientProtocolException

CONNECT isn't mention in HTTP Request component:

GET, POST, HEAD, TRACE, OPTIONS, PUT, DELETE, PATCH (not supported for JAVA implementation). With HttpClient4, the following methods related to WebDav are also allowed: COPY, LOCK, MKCOL, MOVE, PROPFIND, PROPPATCH, UNLOCK, REPORT, MKCALENDAR, SEARCH.

Can CONNECT method be execute in JMeter? if not what can be the fix? change to other method or only remove those requests from script?

EDIT

I also failed in HTTP Raw Request to execute similar CONNECT method.errors: Response message: java.nio.channels.AsynchronousCloseException or java.net.ConnectException: Connection refused: connect

I also failed to change to GET or https protocol.
