Wikipedia lists S200114f (on page https://en.m.wikipedia.org/wiki/List_of_gravitational_wave_o...) in a way that to me makes it sound like there’s substantial uncertainty about the cause of it; is that maybe because Wikipedia is out of date and people figured out the (not unusual) cause since, or is maybe just wrong, or maybe I misunderstand what you mean, or I misunderstood what the people who labeled the entry for it on Wikipedia meant?
The original solution field equation is for a constant speed drive, which I believe does not emit any gravitational waves. I’m not sure how much work has been done on the formation of the bubble and what effects that would produce, or indeed how a ship could change its heading, which are events that I think should produce gravity waves.
