I got my honor unlocked after 2 days

DISQUALIFICATION As announced in August, certain players are ineligible for this season’s rewards:

Players with bans or chat restrictions active when the season ends. Players issued a ban of 7 days or more after Aug 22nd, 23:59 Pacific Time. Players banned for boosting during the 2017 season.

What if I have Honor 2 or below? You’ll get rewards as long as you do not hit the ineligibility criteria above.

Your rewards are not tied to your honor - it is tied to if you were issued punishments. You can have level 0 honor but still receive season rewards, and you can have honor level 5 and not have them (theoretically).

The criteria to be disqualified are either 1) a ban of 14 days of more which began on or after 8/22/17, or 2) an active chat restriction at the end of the season. If you do not meet either of those criteria, then you are eligible for rewards. If one of those applies to you, you’ll be ineligible for rewards. Again, it’s completely independent of your honor - except for the honor ward which is dependent on your honor.
