Possible to take back the disk space that was mistakenly allocated?

I've mistakenly allocated more disk space of 50 GB to the wrong disk.  The VM has 2 disks and I was

intending to add more disk space to disk 1 but ended up adding it to disk 2.

I haven't expanded the mistakenly allocated disk space in the OS.  It still shows up as Unallocated in Disk Management.

Is there a way to delete the unallocated 50GB in ESXi so it frees up the space?

Thanks
