If I plug my phone into an external DAC, does it bypass the internal DAC in the phone?

I’m worrying about possibly bottlenecking the audio quality when I’m playing mp3s and flacs through my phone into a DAC. Just want to make sure wether or not the internal DAC is bypassed. Pls forgive me if this is a stupid question, I’m an analogue guy when it comes to music and audio.

Thanks <3
