Hi I'm using Moto X style and most the space consuming apps are stock Google one which I basically don't use at all. Is there a way to remove them without rooting the device. I know it's an hard ask but I'm just taking a chance here ?
Not a chance, sorry. You cannot remove pre-installed apps (System apps) without write access to
/system – which you won't have without
su (rooting). All you can do is deactivating parts if the Google Apps – you probably cannot even deactivate them all, as some will show up as "protected" (aka "I am too important").
Best way to really get rid of all of them is to flash a custom ROM, which usually comes without GApps.
