Hi @Abhijit Swami ,
As the document mentioned, you could specify {parameter:ListTitle} in your template will translate to 'Projects' when applying the template. These tokens can be used in most string values in a template.
Invoke-PnPSiteTemplate -Path c:\temp\theperspective.pnp -Parameters @{"SiteTitle"="Mysite";"SiteUrl"="/sites/Mysite"}
Here is the document for reference
