Firstly were you careful to have you phone fully up to date when you first installed /e/OS. From a search Moto G7 play latest firmware I found motostockrom – I would look for another confirming source. Edit The search also revealed worldwide-motorola-support and XDA – Moto g7 play Factory Firmware
Then check the Vendor SPL (security patch level) on your phone now. It is the date of your last software revision.
Settings > About phone > Android version > Vendor SPL.
If you are as sure as can be that there is no software revision ahead of the date found on your phone, you will be good to go.
Please share the date you found for the next person facing this decision !
I have been making a case that we try to find a way to keep this info for more devices,
