How do I upload photos on Instagram without IG tracking me?

I'm trying to fill up a few accounts with content , they won't be used for botting just for placeholder.

I'm looking to do 20+ accounts but am worried that if I log in with my phone even on LTE that Instagram will be able to track my MAC ID or something and tie all the accounts together.

Do you have a workaround that doesn't involve getting a bot? I've heard perhaps using apps like TweakBox or AppValley might be the solution.

Honestly I'd just use a cheap automation tool and get this all started than disconnect. Will be most likely easier.

OR

Get 20 buddies to create one each on their phone for you and pay them like a coffee lol. I've done something similar.
