Does periodic trim work on SSD connected via USB 2.0?

It looks like my OS is set to periodically trim portable SSD drives, and TRIM is supported by my portable SSD. I connect this SSD via its usbc cable, attached to the usbc to usb3 adapter that came in the box with it, then connected to the usb2 port on my laptop. Is trim actually executed? I read that trim commands are not supported through usb 2.0... for example here is written that usb2 does not support trim: https://wiki.gentoo.org/wiki/Discard_over_USB (section prerequisites). Also https://en.m.wikipedia.org/wiki/USB_Attached_SCSI says that it depends on the hardware and sometimes usb hub... Does it mean that I have to investigate specifically my motherboard?
