If i create freebsd datasets, can I install without erase preesistent distro? If yes, How?

Yes. Key phrase:

root on ZFS​

We're directed (maybe misdirected) to the FreeBSD Handbook, which has no such phrase, so maybe try the second of the pictured wiki pages.

Thanks, so if I follow the guide without creating zpool (because I've already zpool) and only create dataset for freebsd into zpool that already contain Linux too, I can't lose data right? Another little question, how EFI partition can I use partition on fat32?

You don't appear to UEFI boot this machine. But if you do, you can use the existing efi partition. Just don't let the installer create it, or else you will end up with two efi partitions.

To use an existing efi partition, all you need to do is copy /boot/loader.efi to EFI/FreeBSD/loader.efi and use efibootmgr(8) to add it to the efivars.
 
Ok, I've installed freebsd on pre-existing pool. So, now I can boot freebsd but Linux distros go on kernel panic because can't found zpool
 
Hi all, now I reopen this thread because I've question.
Currently I've freebsd on external disk, but I would to move this on other pool but with openzfs encryption

This is my situation:
Code: 
marco@tsaroo ~ $ zpool list
NAME      SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
bsdpool   476G  2.09G   474G        -         -     0%     0%  1.00x    ONLINE  /home/marco/media
rpool    1.80T   456G  1.35T        -         -     6%    24%  1.00x    ONLINE  -
zroot     952G  2.57G   949G        -         -     0%     0%  1.00x    ONLINE  /mnt

where rpool is linux pool (where I boot in this moment), bsdpool is freebsd pool and zroot is pool where I want bsd.
zroot is create with native encryption
This are datasets situation:
Code: 
marco@tsaroo ~ $ zfs list

I migrate dataset of freebsd with zfs send, but at reboot didn't boot bootloader.
Have you some advices for my situation?
