If you're on the computer, you can just use Nostrudel and setup a local relay as an app relay for writing. Then you can toggle the writing on-and-of.

If you're on Amethyst on Android, use Amber and Citrine, and then you can write only to your local relay, by selecting it in the writing form (click on the symbol above the text-entry field) or by adjusting the settings in the relay management page.

But, increasingly, the relays themselves are going to allow you to define what goes where and to whom.
