Is the Guest WiFi Isolation Feature in the room with us.

[Kevin O]

is there's any way to isolate R3 guest wifi from the main local network, make it so guest clients can't use/see my printers, Apple TVs, speakers, shared local folders. I know  other DUMAOS routers are able to do it eg. XR1000. I think I'm done with R3 and ordering an ASUS GT AX-11000. I like the UI of DUMAOS 4  but the lack of features like these is pushing me away.

C’est le principe du Wifi invité ! 
Il est est isolé du réseau local… tous périphériques sur le réseau invité ne peuvent interagir / voir les périphériques sur le réseau local.

Y a t il quelque chose qui ne fonctionne pas ?

The issue is that the guest WiFi is not isolated on the R3 router.

I was able to see and use my printer and appleTVs while my 2nd Iphone was connected to the guest WiFi, the printer/appletv were connected to the main WiFi.

Not specifically no. You may be able to do some of these things by setting up Internet Rules for a specific guest device for example to block file sharing, printers etc
