You would do something like

--8<---------------cut here---------------start------------->8---
(connection-local-set-profile-variables 'remote-direct-async
   '((tramp-direct-async-process . t)))

(connection-local-set-profiles
   '(:application tramp :machine "randomhost") 'remote-direct-async)
--8<---------------cut here---------------end--------------->8---

`remote-direct-async' is a profile name you could choose
yourself. `tramp-direct-async-process' would be the respective Tramp
variable.

Best regards, Michael.
