The default option in WhatsApp is to back up all your messages and photos to Google Drive and also to Internal Storage of your Android Phone.
Also, if your Android Phone has a MicroSD Card, WhatsApp automatically makes use of the SD Card to Backup your Messages, instead of using the internal device storage of your Android device.
Hence, all that is required to Backup WhatsApp to SD Card is to initiate a manual Backup of WhatsApp on your Android Phone.

You can follow the steps below to initiate a manual backup of WhatsApp to SD Card on your Android device.
1. Open WhatsApp > tap on 3-dots menu (top-right corner) and select Settings in the drop-down menu.
2. From the Settings screen, go to Chats > Chat Backup > select Backup to Google Drive option located under “Google Drive Settings” section.
3. On the pop-up that appears, select the Never option.
