How get ID of modern Site Features

Question

I am using site designs to create new site collections attached to a hub site with the appropriate features enabled, now I seem to have hit a wall between classic and modern features. I have an action to activate features such as Project Functionality.

Example:

{
    "verb": "activateSPFeature",
    "featureId":"e2f2bb18-891d-4812-97df-c265afdba297"
}

I would like to now remove some features, Specifically the "Site Pages" feature to stop the end-user from creating site pages on a particular set of site collections. However, I do not seem to be able to find the GUID of the "Site Pages" or the "Mobile Browser View" Feature.

Does anybody know how I can find this?

I have tried to use the PnP cmdlet however this only provides me with classic features, cmdlet used:

Get-PnPFeature

Any help would be appreciated - It seems to me there is a missing link connection to be able to pull the properties of these features.

Thanks in advance!

You can prevent a web from using the "modern" page experience by disabling the web scoped feature with ID B6917CB1-93A0-4B97-A84D-7CF49975D4EC (name = "Site Pages"). To re-enable the "modern" page experience at the web level, you need to activate the feature again.

Note:

When you disable the feature, you can no longer create new "modern" pages, but the already created pages stay working using the "modern" user experience.

Source: Web level configuration.

If you want to completely disable the "modern" experience, it's best to use the tenant setting for this. Go to your tenant admin center (for example, contoso-admin.sharepoint.com), go to Settings, and select the "classic" experience.
