Bathroom bonding with enclosed pipes

[DJM]

I have a shower room with the following supp bonding

I now intend boxing in the header tank pipes to tidy up the room. They will be fully enclosed and inaccessible from within the bathroom without use of tools (probably a crowbar, hammer and screwdriver). Therefore, do I still need the 3 header pipes bonded? and should I

1) Remove bonding on 3 header pipes only completely as pipes are not strictly entering the room and can not be touched by shower room user
2) Leave bonding on 3 header pipes in place and box in most of pipes, but leave part of pipes where bonded visible
3) Leave bonding on 3 header pipes in place with pipes fully enclosed but unscrewable access hole to where pipes are bonded
4) Leave bonding on 3 header pipes in place and fully enclose pipes

Thanks

(Editied to clarify I was uggesting removal of bonding on the 3 header pipes to be enclosed only. All other bonding remains as is. Sorry for any confusion)

Don't do no 1 without ensuring everything complies with the rules in the 17th edition as otherwise the bonding is still protecting a person in room from potentials across electrical and other exposed extraneous metalwork such as the shower head, taps etc etc.
2 or 3 is acceptable
4 could be acceptable but that would involve making the connection permanent as opposed to a clamp, information would have to be made available too.

Edited original post to clarify I was not suggesting removing all bonding and define which bonding I was talking about removing

Spark123's reply was before I edited, and I am not sure I understand why removing the bonding from just the three pipes is an issue. Once they are enclosed they will be in a permanent feature and therefore in the same state as a pipe passing behind a partition wall. The bathroom user can not touch them and therefore be at risk from a potential difference between them and the other metal elements in the room.

I don't have any issue with leaving the bonding, but would prefer not to leave inspection holes as that obviously defeats the object of boxing them in.
