ARM Template Functions with PowerShell TemplateUri TemplateParameterObject

Question

When I use an ARM template and define a parameter _artifactsLocation with a default value of "[deployment().properties.templateLink.uri]", it uses the ARM Template deployment function and works well. If I define a hashset and send in the same string, the string gets evaluated as a literal instead of running the template function.

Is there any way around that? (Any way to use a template function with a PowerShell parameter?) Thank you!

 $templateParameters = @{
        _artifactsLocation = "[deployment().properties.templateLink.uri]"
        _artifactsLocationSasToken = ""
    }
