How to schedule a Power BI Report Automatically to Email In PDF Format

You cannot schedule reports. You can schedule dataset refreshes.

I think what you are asking is if you can schedule report extract to PDF. The answer to that is yes.  Use either Powershell or Power Automate to issue the required REST API commands.  Be aware that this is a multistep process

- request a dataset refresh (optional)

- monitor dataset refresh status, wait for completion (optional)

- request extract of report to PDF

- monitor rendering completion, wait for the file to be ready

- retrieve the rendered PDF

- attach it to the email and send the email.

All this can be done in Powershell or Power Automate - or whatever automation tool you prefer that can issue basic HTTP commands.
