no. you need to have linux installed on your raspberry pi first. I use Debian Bookworm Lite (without a UI, just shell). then install the meshtastic stuff on top of it. Meshtastic has a web interface that will install on the pi, so you can then have a web based UI to configure the lora settings. You can see Bookworm Lite on the Raspberry Pi imager in the "Raspberry Pi OS (Other)" section:
