Try this:

Import-Module IISAdministration -Force          # you may not need to explicitly load this module
$site = Get-IISSite -Name "<site-name-name-goes-here>"
$app = $site.Applications | 
            Where-Object {$_.Path -eq "<application-path-goes-here>"}   # has leading /
[string]$protos = $app.EnabledProtocols
$protos += ",<additional-protocol-goes-here"    # NOTE LEADING COMMA! the list is a string of comma separated values
$app.EnabledProtocols = $protos
$m = Get-IISServerManager
$m.CommitChanges()
