of course you can. Depends on what property or configuration you actually want to change.
Just to name an example, have a look at "sp_configure".
Changing the name of a sqlserver can be done using sp_dropserver and sp_addserver. Just google for it.
Have you learned about the Script button in SSMS? It will help you to review what will actually be run against your instance to ensure you know what is happening as well as help you save the change for later use in production after you have tested the change in a non-produciton environment
Personally I never apply changes using the GUI's OK button. I may make the configuration change in the GUI but then I will always script it to a query window using the Script button and then Cancel the GUI dialog. Then, after revieing the script generated by the GUI, if I agree with the code and want to make the change I will run the script.
