dnd 5e – Hide an artifact

In my dnd 5e campaign my players have found an artifact, to be specific a “necronomicon” which is more or less a spellbook, and now they carried it around

Most of the abilities of the book are already known to the players

1.) The main purpose of the book is to be found (and read) – this is its primary goal, everything else is secondary.

2.) because of that its magic trace always can be detected – for now they keep it in a led box within a bag of holding – even then people in a radius of approximatly 50 feet can detect or react to the books aura.

3.) Once completly read it basically starts the eventchain for Ragnar̦k Рthe destruction of the current era to move on to the next one

4.) It also contains all 7 great evils – they already “destroyed” azmodan.

5.) In order to destroy it they would have to destroy the Far Realms, so basically a whole plane – not really an option yet for them since they are lvl 10

Since the book bugs them more and more they are trying to hide it now – the bag of holding combination is barely working for them and more and more monsters are chasing them for the book and they are getting pretty much super annoyed by it.

So I was thinking of a logical way how they actually can get rid of the book without “returning”, but i don’t want to “gift” it to them.

A few things I already ruled out:
Just hiding it on another plane,
Dumping it in the sea/volcano/forest/whatever,
Giving to some strong npc that knows about the book, since the book can corrupt even the strongest and kindest mind

Is there any “smart” way to actually get out the book of their way for atleast a few sessions so they stop going crazy about it, so i could give them a “little hint” in order to figure it out themselves.

Main Reason for this: The gamesessions are getting more and more about discussions how to get rid of the book instead of actually playing – which is very annoying in the long run for both sides.
