H810 JBOD and boot issue

Hello i have two issues with our H810

First, i would like to use it in JBOD mode, multiple official documents calims it has this possibility. Trough perccli show all command i can see:

Enable JBOD = No

also via command to allow JBOD i get

root@debian:~# perccli /c0 set jbod=on
Controller = 0
Status = Failure
Description = None

Detailed Status :
===============

-------------------------------------------------------------------
Ctrl Status Ctrl_Prop Value ErrMsg                           ErrCd
-------------------------------------------------------------------
   0 Failed           -     Controller does not support JBOD   255

-------------------------------------------------------------------

root@debian:~# perccli /c0/e91/s20 set jbod
Controller = 0
Status = Failure
Description = Set Drive JBOD Failed.

Detailed Status :
===============

-------------------------------------------------
Drive       Status  ErrCd ErrMsg                 
-------------------------------------------------
/c0/e91/s20 Failure   255 Operation not allowed.
-------------------------------------------------

 

So it does not suppor JBOD at all am i right? I googled a lot for this definitive answer and i want to be sure before i say i to my boss.

Second:

We use this H810 in Supermicro server and i cant get Ctrl + R option during boot, so i cant get to PERC menu. Is there any other way how to get to PERC GUI or mabye some hint how to fix this?

Thank you
