Is it possible to completly disable ibus and use xkb only

Is it possible to disable ibus completely on Silverblue (33)/Gnome, and only use xkb layouts?

My preferred configuration is:

XKB_DEFAULT_LAYOUT=us,mk
XKB_DEFAULT_OPTIONS=grp:switch,grp:caps_toggle,grp_led:caps

Will the layout indicator in Gnome work?
