How to enable custom scripts in SharePoint SE (OnPrem) on Modern Design site collections

Question

Is it possible enable custom scripts in SharePoint SE (OnPrem) on Modern Design site collections? In 2019 it was possible for site collections in Classic Design, see https://sharepoint.stackexchange.com/questions/272451/sharepoint-2019-how-do-i-embed-custom-script, and it seems to be possible in SharePoint Online (https://learn.microsoft.com/en-us/sharepoint/allow-or-prevent-custom-script), but how can we do this in SE for Modern Design pages?

Hi @Matthias68,

Thanks for reaching out to us. We are very pleased to assist you.

Unfortunately, after we enable the custom scripts in SharePoint SE (OnPrem), the Script Editor Web Part and Content Editor Web Part are not available in SharePoint Modern Pages.

These web parts were part of the classic SharePoint experience and were primarily used in classic SharePoint pages. In the modern SharePoint pages, Microsoft has moved towards a more simplified and secure way of structuring content, and custom scripts aren't allowed directly on these pages.

Currently, the only way to add custom scripts to Morden experience site collection is to use SPFx.

If you are new to SPFx, then you can start with this article: SharePoint Framework development with SharePoint Server 2019 and Subscription Edition.

We also recommend using SPFx, as the “Allow custom scripts” setting will be removed in the near future. Once this is removed, we will not be able to use custom scripts in Classic or Modern Experience and SPFx will replace them as another option for customizing SharePoint.

If you have any questions, please do not hesitate to contact me.
