Bringing MacBook running OCLP at Apple Store.

I recently bought a maxed out 15-inch 2015 MacBook Pro for cheap. I wanted to see if I could get a free battery replacement from Apple as certain 2015 models were recalled in 2019. Luckily my MacBook qualifies and I’m bringing it in this week. I bought an nvme drive for it and was planning on installing it tonight along with Sonoma using OCLP. Would they no longer repair my MacBook seeing it is modified? Would it be best I just wait till the repair is finished? Has anyone had any experience with bringing modified MacBooks to the Apple Store?

Thanks!!
