C# WinForm Desktop App - Connecting Client to Server IP in A

Goodday Programmers, I just finished developed a C# WinForm desktop application I created the Standalone Setup( with mssql DB) nd it is working fine when i run it....now the issue is running it on other Client computers I already installed the Setup on other Client computers, how can i change the App Config settings to point to my Server laptop IP and Port 1433 ? I mean Changing(Picking) to Server machine IP and SQL server Port 1433 at the point of Setup Installation on Client machine ... because i have already created the Setup and it cant be edited Both are on the same LAN network
