How to get Evri parcels delivered next day for SFP

We’re a UK-based Amazon seller and we’re trying Seller Fulfilled Prime. We already use Evri and have a shop down the road where we drop off parcels at the end of the day. However, their Evri collection can be any time from 11-4, so we’re not always able to drop off next day parcels before they are collected from the shop.

How do we receive a next day Prime order at 4pm and still get it delivered by Evri the next day? Are there big Evri depots we need to use?
