which ISO should I select from the repo?


You should provide the pci id of the device...

Anyway main download link is here:
https://elrepo.org/linux/dud/el8/x86_64/

and probably it is the latest dd_meagraid_sas.iso file like this:
https://elrepo.org/linux/dud/el8/x86_64/dd-megaraid_sas-07.717.02.00-1.el8_5.elrepo.iso

I have not an hw like yours, but for example on a PowerEdge R730 with RH EL 8.5:
# lspci | grep RAID
03:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3108 [Invader] (rev 02)

and then query the kernel module used for that ID (03:00.0 in my case):
# lspci -k -s 03:00.0
03:00.0 RAID bus controller: Broadcom / LSI MegaRAID SAS-3 3108 [Invader] (rev 02)
DeviceName: Integrated RAID
Subsystem: Dell PERC H730P Mini
Kernel driver in use: megaraid_sas
Kernel modules: megaraid_sas
