How to set SpaProxyServerUrl based on environment in .net core 6

In the SPA project Angular 13 with Asp.net Core 6. I want to set the SpaProxyServerUrl based on the environments like Dev, Stage and Prod. In the csproj file i have the code as below. Can we able to set the property "SpaProxyServerUrl" in program.cs file or is there any way to set the value dynamically based on the environment?

<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
<Nullable>enable</Nullable>
<IsPackable>false</IsPackable>
<SpaRoot>ClientApp\</SpaRoot>
<SpaProxyServerUrl>http://localhost:4200</SpaProxyServerUrl>
<SpaProxyLaunchCommand>npm start</SpaProxyLaunchCommand>
<ImplicitUsings>enable</ImplicitUsings>
</PropertyGroup>
