How does POSTMAN quickly clear the DNS cache?

my development environment and online environment use the same domain name. Usually use SwitchHosts to switch environments,
but there will be caches in each browser software. In chrome , I use ctrl+shift+del to clear the cache.
postman built-in browsers do not support this function. I have also tried to set no cache in the request header, but it has no effect at all!
can only refresh the dns cache by restarting postman , which is very troublesome.

in the latest version of postman , there is even a conflict. Restarting postman cannot flush the dns cache, nor can it clear the cache in cmd.
I hope the experienced boss will take a look at it for me.
