Problem is that you can list all files in workspace only via API call and than you can run every one of them using:

dbutils.notebook.run()

This is the script to list files from workspace (probably you need to add some filterning):

import requests
ctx = dbutils.notebook.entry_point.getDbutils().notebook().getContext()
host_name = ctx.tags().get("browserHostName").get()
host_token = ctx.apiToken().get()
 
response = requests.post(
    f'https://{host_name}/api/2.0/workspace/list',
    headers={'Authorization': f'Bearer {host_token}'},
    data = {'path': '<your-path>'}
  ).json()
