bhyve - Linux VM w/ boot NVMe SSD - VirtIO vs AHCI

[trickster]

Hello,

I've been testing VirtIO vs AHCI disk device settings with the latest version of Debian. I noticed with VirtIO, TRIM was not detected, while it was with AHCI.
And out of the box, TRIM is supported & enabled for my NVMe device.
Question: if the FreeNAS host is handling TRIM, should I even worry about it in the VM?
If I should worry about it in the guest OS, would you take advantage of the sequential performance boost of VIO or be conservative and use AHCI mode while using a scheduler such as deadline more suited for slower SATA SSDs?

Thanks in advance for the advice!

Forgot that to add that I'm running 11.1-U6 on the host
