I have got a wrapper script which calls another powershell script that then calls a bicep deployment, I would like to implement a solution where I am not specifying the path of the file, as the solution would be moved onto github actions, with the current setup I have hardcoded the paths

.deploy.ps1 `
    -DeploymentResourceGroup 'my-rg' `
    -TemplateFile 'C:ABCDmain.bicep' `
    -ParameterFile 'C:ABCDEenvsdev.json' `
    -rbacTemplateFile 'C:ABCDrbac_roles.bicep' `
