Inquiry About Adding Company Watermark to ServiceNow Main UI and Service Portal all Pages

Our ServiceNow instance is self-hosted (on-premises). We want to add our company watermark to all pages, both in the Main UI and the Service Portal.

I reached out to ServiceNow, and they confirmed that there is no out-of-the-box (OOTB) functionality or method to achieve this.

Are there any recommended custom methods to meet this requirement? Any ideas would be greatly appreciated.
