Assuming that the oem unlock switch is activated before the update of course
Download your firmware. When you extract the downloaded file there will be 2 CSC:s files.
CSC - will wipe your phone
Home_CSC - will keep your data
Flash with Odin all files using Home_CSC.
Inportant Note: Backup first.
If you are having issues with using the Home_CSC try from recovery clear cache/davlik or you will have to factory reset or reflash using the CSC file.
You will have to reinstall trwp and magisk.
OEM lock has no bearing when flashing stock firmware.
