how can i return tcp in django to confuse nmap?

nmap scan send with the request 0 headers, so

if not request.headers:
   print("nmap scan me")

than django send him http response back and nmap know this is http and start http scan

but if i send him back tcp connection he cant say that this is a http scan and he wont scan my website

however if i do something like return b"hi i return bytes" i get an error

so how can i return tcp response instead of http response
