I verified with 
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ath10k/WCN3990/hw1.0/board-2.bin

$ strings board-2.bin | rg oneplus
bus=snoc,qmi-board-id=ff,qmi-chip-id=30214,variant=oneplus_sdm845mmm

$ ./ath10k-bdencoder -e ~/Downloads/board-2.bin
...
bus=snoc,qmi-board-id=ff,qmi-chip-id=30214,variant=oneplus_sdm845.bin 
created size: 19152
...

Since OP6/6T should have same WiFi.
