Perhaps not the best options but just another way is to read the Windows Registry in the host machine, on elevated PowerShell prompt you can do something like this:

#Get SQL instance's Port number using Windows Registry:
$instName = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server').InstalledInstances[0]
$tcpPort = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\$instName\MSSQLServer\SuperSocketNetLib\Tcp").TcpPort
Write-Host The SQL Instance:  `"$instName`"  is listening on `"$tcpPort`"  "TcpPort."

Ensure to run this PowerShell script in the Host Server (that hosts your SQL instance / SQL Server installation), which means you have to first RDP into the SQL Server/Box/VM, then run this code.
