How to find list of Sharepoint hidden sites (programatically)?

I have a Sharepoint Online tenant with number of sites. Some of those sites marked as hidden ("Allow this site to appear in search results?" is no) and search query in the Sharepoint to search for sites doesn't returns them at all, while sites that are not "hidden" returned. Is there any way (programatically, REST / Graph API) in the Sharepoint Online to search for such "hidden" sites and get list of them ?

Thanks
