Timeshift on boot timer

Ehi guys,

so i installed timeshift and set it up to run at boot and before a system upgrade

i used the timeshift-systemd-timer AUR package as a timer for the "on-boot" trigger

i noticed that it waits 10 minutes after boot by default before running the snapshot:

[Timer]

OnBootSec=600

Persistent=true

So the question is, i don't want to eventually start a heavy game on boot and after this 10 minutes it start doing this snapshot,

i know this timer is to assure that every file system is mounted but it seems a bit too much.

What is the minimum i should put it to not mess with it?
