Not hard code end point in Apex callout

Question

I am using named credentials to store the username password for apex callout. In my apex class. I am storing using the below code to use the named credentials. Is there way not to hard code some_path URL in the code? Link - https://help.salesforce.com/articleView?id=000206791&language=en_US&type=1

HttpRequest req = new HttpRequest();
req.setEndpoint('callout:My_Named_Credential/some_path');
req.setMethod('GET');
Http http = new Http();
HTTPResponse res = http.send(req);
System.debug(res.getBody());

I often use a Custom Label to make string values configurable in my code:

req.setEndpoint(Label.My_Credential_Name);

You can also always go to Custom Settings when you want to make parts of your Apex code configurable:

• List Custom Setting

  MySetting__c myCredential = MySetting__c.getInstance('Some Name');
  req.setEndpoint(myCredential.Path__c);
  

• Hierarchy Custom Setting

  req.setEndpoint(MySetting__c.getOrgDefaults().My_Credential_Name__c);
  

You might also consider Custom Metadata Types, which would operate similarly to the List Custom Setting approach.
