Disable iOS Safari lock screen scrubber for media

Safari on iOS puts a scrubber on its lock screen for simple HTMLAudioElements. For example:

const a = new Audio();
a.src = 'https://example.com/audio.m4a'
a.play();

JSFiddle: https://jsfiddle.net/0seckLfd/

The lock screen will allow me to choose a position in the currently playing audio file.

How can I disable the ability for the user to scrub the file on the lock screen? The metadata showing is fine, and being able to pause/play is also acceptable, but I'm also fine with disabling it all if I need to.
