Disable pixels for wordpress administrators

Any way to disable executing pixels when wordpress web site is accessed by wordpress administrators?

I think our FB statistics is reporting purchases when our WP admins are making purchases on behalf of our clients (because our WP admin had opened FB ad some time ago, now FB pixel thinks all his actions on our web site are refered by that FB ad).

I checked that FB is not providing any way to exclude internal traffic from their analytics (not even IP filter). So the easiest solution would be to disable showing FB pixel if user is logged in web site as WP admin.

Can we add a script to do it?
