Whitelist IP addresses on Google sites, which are used as startup pages on Chromebooks

[MortenUlstrup]

From the Google admin, we push out fixed startup pages to the Chromebooks of staff and students, to create a user-friendly IT environment.

Here is an example on a staff home page: https://sites.google.com/gskole.dk/sondervang/forside 
And here an example on a student start page : https://sites.google.com/gskole.dk/skolerneiglostrup 

Since all Chromebooks open these pages many times a day, 2 days ago we got this message

Could it be possible to Whitelist the IP addresses from within the Google admin from which these pages come, so that we do not have this problem in the future

Many greetings
