Is there anyway to patch /apex using Magisk?

As part of Project Mainline, Google decided to pack a number of files in .apex modules which are located in /system/apex which upon boot, are extracted and mounted in /apex. For example: the contents of /system/apex/com.android.tzdata.apex file will be mounted at: /apex/com.android.tzdata Is there any way for patching (overriding) the contents of mounted .apex files using Magisk?
