In case you want to change your Dynamics 365 Finance and Operation Env URL

if there is a case you want to change your env URL in later point of time (rarely happens).
this is not straight forward like Dynamics 365 CE.
in FO you got to re create the env.

login LCS -> STOP the env -> Deallocate the env -> Delete the Env. after that you will get the Configure button over there  and reconfigure as per new URL.

NOTE: take note if you will do above, you will be loosing your data.
Hence take back up first and then you can restore those into the new env.
