Giant-Liv experts: Liv Avow Advanced 0 2017 UCI legal without the aero add-ons?

Looking for a UCI legal frameset.
I got this Liv Avow Advanced pro 0 2017.
My question is : without all the aero add-ons in front of the head tube, behind the stem, under the BB. Is this frame UCI legal ? It’s not on the homologation list. The last Giant TT bike to be homologated in TT was the 2015 Trinity. I’m surprised by this.
But still Liv-Jayco-Alula women’s cycling team is using it (the last iteration) as their TT bike.
Some of you guys have raced this frame at UCI level races ?
Thanks for the info.
