If you don't know, this was originally played by a synth. That being said, I think it's a nice bass line.
I assume you are playing on a detuned 4-string rather than an extended range instrument with low B.
What fingering system do you use?
What part of the lick do you find challenging?
I use One Finger Per Fret and the lick as notated is fairly easy, but it requires me to modify my technique. I play mostly on my finger tips. With this lick I bar the 4th finger, 3rd finger, and 1st finger. I play this all in one position without any pivots or shifts. However, I have to reset my hand shape a bit for each fret. In other words barring 4, barring 3, barring 1 all require different hand shapes. The lick as I play it is somewhat taxing, but that is okay because it's only played occasionally.
If necessary, you could consider simplifying the line or make up something else that fits. I doubt anyone will notice but other bass players. Then you can point out it's a synth part.
