yes you can. you can setup a feedserver pointing to tmp/deploy/ipk in
your workspace

something as simple as cd tmp/deploy/ipk && python3 -m http.server 8000

will do it. Once you have it then setup the feed on your device to
point to this server
something like

https://github.com/cbrake/oe-build/blob/master/envsetup.sh#L480-L489

then you can do normal opkg operations

if you are able to rebuild the whole image then step to edit feed
confs is not needed
you can add

PACKAGE_FEED_URIS = "http://<ip>:<port>/" in local.conf

where ip is the local address of your build machine and port is the
port on which you
are starting the http server.
