[Need Info] Intel RST and NIC in P8B-X v2 BIOS

Hi, I have a few questions about the Intel RST BIOS version of the ASUS P8B-X motherboard. The current version of the C202 chipset RST and the dual NIC W82574L in the BIOS version 6801 are:

Intel(R) RST 11.6.0.1702 SATA DRIVER
Intel(R) PRO/1000 5.3.00

I want to upgrade the HDD for SDD (still in RAID1 mode), but I worry about the TRIM function that can be missing in RAID1. Is the RST version above supporting TRIM in RAID1 mode? If not, is there a more recent version supporting this? As for the NIC controllers, I want to use them in Teaming. Not tried already, just asking if current BIOS version is compatible with NIC Teaming in Windows Server 2019 (for 2Gbps). Anyway, is there advantages to upgrade to a latest version (if any)?

I know this is an old mobo, but I want to revive it a little. Sorry for my bad English.
