Set a new configuration value
To update a value you need to use the
Set-DbatoolsConfigcommand. Unfortunately, you will not find documentation for this command on our docs page. This is a known issue and it happens because that command is a cmdlet so the help is in the dbatools library itself.
For this particular case, you can and should rely on the
Get-Help -Name Set-DbatoolsConfig -Full
Claudio has a half-dozen or so settings and there are more available to you.
