I had a case where neither the BIOS nor the Linux command line tool
for the LSI controllers (not a PERC) were able to influence the disk
caches (i.e. they were always turned off). But a "disk managemenent suite"
(delivered as a bootable ISO) was able to change the setting.

And yes, these were SATA drives.
