the gag reflex is outgrown. Typically.
each baby being different.
I dont' know that you can actually make it go away, intentionally.
I would ask your Pediatrician.
The reason being, you are running out of expressed milk, and she does not take formula.
Will she direct breastfeed????
For the 1st year of life, breastmilk/Formula is a baby's PRIMARY source of nutrition... NOT solids and NOT other liquids.
This is also per our Pediatricican.
We, per our Ped., did not give our kids as babies, things like Cheerios or quick dissolving foods until they were closer to 12 months old.
Your baby is gagging/vomiting... on even small pieces, because she still has the gag-reflex and is not swallowing and did not yet attain the mouth/throat/tongue coordination yet, for swallowing/eating/chewing.
WATCH that she does not choke. This is a danger. Or aspirate her food.
Also, she should be trying pureed baby foods... ie: not "apples" but apple sauce. A baby, even a 2 year old toddler, can choke on apple chunks or even bits. For a 1 year old even, foods have to still be only the size of a pea... or minced.
She could also be teething... which at these times, some babies seem to 'reject' eating/nursing. Because it is uncomfortable.
She also does not seem ready to 'eat' solids, and clamps her mouth shut.
I would hold off.
Solids is not their primary food, at this age, anyway.
Try direct nursing her.
Ask your Ped for suggestions... since she is not currently intaking anything much.
Babies at this age and for the 1st year, still need to feed/nurse on-demand.
Watch out that she does not get dehydrated either. Per her diminished intake.
Here's a good link on solids/feeding:

Again try to direct nurse her, instead. If you are giving expressed milk to her, instead of direct nursing, your milk production will diminish. And this will cause "weaning" in your baby. And you don't want this. Because, at 6 months, 9 months, every 3 months, this is a growth-spurt time. And they need increased intake, breast or Formula.
Direct nursing, will increase your milk production. Maybe then you will not run out of expressed milk.
I would try and work on increasing your milk production.
If possible.
A baby needs to drink/feed, whether by breast or bottle, on-demand and to keep up with their growth-spurts.
How much intake is she getting?
For me, that would be more of a concern...
All the best,
Susan
