I haven't played in a while and when I started up again recently, I now receive the Azure Festive Steed for free with each new character along with various cosmetic adds for it including the accessory add which is a banner.

Unfortunately, I don't like the way the banner looks but have already "consumed" the item and added it to the steed.

Is there a way to hide this accessory before I have access to the War Steed cosmetic screen at a much higher level? (My new character is currently level 28.)

Any thoughts would be much appreciated. Thank you!
