How to turn off background music when my own videos play on iPhone's Photos app?

In the past it was possible for me to view my own foreign language-study videos on my phone, by importing them into iTunes. But with the change of iTunes to the TV app, that no longer seems to be possible. Instead, Apple suggests storing them in Photos. But upon playback on the iPhone, Apple turns on background music of its own choosing, which drowns out the sound of the videos I am trying to learn from. Very silly design choice. - **Question 1**: Is there any way to turn off the background music permanently? Apple agents don't seem to know of one, but perhaps the community here has an idea. (There have been user complaints about it on Apple's Support site, going back to 2021.) - **Question 2**: Another idea would be to upload an MP3 containing only silence, to be used as "background" music. But it appears there is no way to select any background music other than the few that Apple has chosen for this purpose. Any thoughts?
