Hi @nellie ,

Please refer the following code snippet to create site page from custom template:

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using Microsoft.SharePoint.Client;  
using ClientSidePage = OfficeDevPnP.Core.Pages.ClientSidePage;  
using System.Security;  
  
namespace CreatePageFromTemplate  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            string userName = "user@Tenant.onmicrosoft.com";  
            string password = "**************";  
            using (ClientContext clientContext = new ClientContext("https://Tenant.sharepoint.com/sites/SiteName"))  
            {  
                SecureString securePassword = new SecureString();  
                foreach (char c in password.ToCharArray())  
                {  
                    securePassword.AppendChar(c);  
                }  
  
                clientContext.AuthenticationMode = ClientAuthenticationMode.Default;  
                clientContext.Credentials = new SharePointOnlineCredentials(userName, securePassword);  
  
                // Load the template page  
                ClientSidePage page = clientContext.Web.LoadClientSidePage("Templates/MyTemplate.aspx");  
  
                // Create and Save the modern page based on the template  
                page.Save("IT_Australia1.aspx");  
            }  
  
        }  
    }  
}  

After saving a page as template, SharePoint Online will create a folder named "Templates" to store the page template like this:

So get this template and then save into another page name will create the page based on this template.

Here is a detailed code demo, I suggest you can refer:
