How to change delivery time for ALL products with same delivery time

[DRMasterChief]

Hello,  how to change delivery time for ALL products with same delivery time?  E.g. i have products with an delivery time given with  2 days and products with 5 days.

Now how to change the 2 days into 3 days?  The  5 days should be not affected.

Is there any entry in the database which we can use?   I already tried to search for something, but i was not successfull  (only hints to bulk update modules, but i want not to use a module for this).

thank you

I thought delivery time was a feature of the carrier, not the product?

I mean the setting which is in each product (below quantity settings),  maybe this is only when AEUC module is used??

Hello, thank you for your idea.  It is not the question why or if this is meaningful,  the question is just about technical solution -  thank you for any hints in this technical direction  😉
