How do I take an indoor pic on my iphone 8 without using a flash?

Turn on every light there's in the place and hope it's enough.

Turn the flash off. Or cover the flash with your finger when taking the picture. Since we don't know how much light there's available, we have no way to know if the captured image will be useful to you.

Disable the flash.

Turn the flash off and keep the camera very steady while taking the photo.

When you turn on the camera there should be a icon present at the top to disable the flash.
