MS graph - query to get sites using the relative path name and more

Hi there,

I want to be able to get some sites in a tenancy but not just based on the name of the site but using a relative path.
Is this possible...

Currently i can use the invoke HTTP and i can get some sites back by doing this below

https://graph.microsoft.com/v1.0/sites?search=ABC&$top=50

But it gets some sites back but not sure what the search here is doing but i can see some other sites are also returned which is not ABC. I want it to search using the server relative path
The question though is how can I use something like the below in power automate

https://graph.microsoft.com/v1.0/sites/mysite.sharepoint.com:/sites/ABC

What i need where is to be able to search for  sites that contains ABC at the end of the above URL

Is this possible?

The documentation here https://docs.microsoft.com/en-us/graph/api/site-getbypath?view=graph-rest-1.0 doesn't help at all

One last question is can get the following values below when i use graph via power automate?
- Owner
- Template
