Is there a device that allows keyboard control or mechanical keys to bypass touch screens?

Yes. A Bluetooth keyboard can be paired with most devices that accept text input. People who are blind often use screen readers and navigate using a keyboard. When connected to a smartphone, they can use familiar keys—such as Tab, arrow keys, and a standard QWERTY layout—to move through the interface.

This approach is also useful for keyboard-only users who have difficulty with touchscreens, allowing them to bypass touch input and use a keyboard instead.
