I'm using vocore2, and present the boot time of my vocore2 running OpenWrt 19.07.3 is 30seconds, I want to decrease it by 10 seconds, while going through dmesg log I found starting ethernet takes around 7sec, so disabling ethernet will decrease boottime by 7sec.

Change your board config to delete those ethernet port. From the result I found in google. This board is coming from this patch

From the boardconfig patch, it seems that the esw block is the ethernet config for this board. Remove it could work. I didn't tried any board from vocore2. Please take your own risk if there is no other recovery method than the ethernet port.
