You can activate TRIM with trimforce.
This command activates TRIM for every single SSD on your Mac. It disables the check that only allows TRIM to work with Apple-provided OEM solid-state drives.
After you run it, TRIM will be enabled for all your solid-state drives. There is no way to enable TRIM for one SSD and leave it disabled for another.
To run trim force, open a Terminal window (press Command + Space, then type: Terminal, and press Enter to launch a terminal via Spotlight).
Type the following command into the terminal window and press Enter:
Your Mac will immediately reboot after you agree to the second question with a y. After it reboots, TRIM will be enabled for all SSDs connected to your Mac.
Here's my System Information window showing that TRIM Support is now Yes (enabled) :
Realistically, this should work properly with most SSDs on a Mac, just as enabling TRIM works properly for most SSDs on Linux. But there are a few outliners, and Apple doesn't want to be responsible if your SSD's hardware doesn't implement TRIM properly and you run into problems.
Let me know what do you think about this by commenting down below.

If you ever want to disable trim force and only use TRIM for Apple's OEM solid-state drives, open a Terminal window again and run the following command:
