I'm trying to install TLS module of Powershell. I can see this module with command:

$> Get-Module -ListAvailabe TLS

    Directory: C:Windowssystem32WindowsPowerShellv1.0Modules

There is no module by that name in the MS powershelgllery.com, to install.

Find-Module -Name '*tls*'

This...

Get-Module -ListAvailable TLS

... is finding and loading modules, already on your system (in your $env:PSModulePath) for use, is this.

Import-Module -Name TLS

Or do this

Get-Module -ListAvailable TLS | 
Import-Module

Update as per your comment about not seeing the cmdlets https://docs.microsoft.com/en-us/powershell/module/tls/?view=win10-ps

WS2K16 Win10 required.
