How to enlarge Windows 10 EFI partition

My system currently has this partition setup:

I would like to enlarge /dev/sdb2, the EFI System Partition, to 500MB.

The problem is that I do not want to delete the Windows Recovery Partition (/dev/sdb1) and I do not know how to move the unallocated space after /dev/sdb4 to be adjacent to /dev/sdb2.

Using Linux, I can move the /dev/sdb4 partition to the right by 400MB, but then I cannot move the MSR (/dev/sdb3) as it is of unknown format.

Using Windows, I cannot move the Windows10 partition, and by the way the MSR partition seems hidden so I cannot act on it.

So I'm stuck with only 100MB of EFI partition which is totally insufficient for multiple keels.
