no, because it's NOT installed.
it's only files located on SD or USB that you load.
The purpose of neek is on the contrary to prevent brick by redirecting all internal NAND file access to external copy of the NAND (on Sd or USB). it's preventing brick, not creating it.
the Sneek installer is a computer app, not a Wii homebrew.
the only thing you can install on the console is a channel (usually called Nswitch) with a wad manager like any other channels.
that channel is used to load sneek files from SD or USB.
Personally, I don't recommend that channel on NAND, I prefer using USBLoaderGX which boots differently and faster (of course you have to go in USBGX first, so it's not necessarily faster if you don't usually use it)
But I think there is a new version of nSwitch working like USBGX (or even better!). I didn't try it.
Without USBGX, using old nSwitch version:
Load Nswitch > load Bootmii IOS (you need it!) > loads SD:/bootmii/armboot.bin > load SD:/sneek/kernel.bin (based on either Sneek or Uneek) > if uneek you also need usb1:/sneek/kernel.bin
If you used Sneek and you want Uneek, you need to replace SD:/bootmii/armboot.bin and sd:/sneek/kernel.bin file with the USB version on SD, you never know which version you really have as they are both named identically.
if you want Sneek, you need the SD version on SD.
if you want Uneek, you need the USB version on SD and the USB version on USB.
With USBGX:
SD:/sneek/kernel.bin <-- that's all you need for sneek. the SD version on SD.
USB1:/sneek/kernel.bin <-- that's all you need for uneek. The USB version on USB.
then USBLoaderGX will load the appropriate kernel.bin file based on your emuNAND location (sd or usb).
note that the two "kernel.bin" are different! the SD don't go on USB, and vice versa.
with USBGX the kernel is loaded right away, without the need of bootmii!
with USBGX you don't need to edit your SD card anymore to replace the kernel with either sd or usb version.
If you use Neek2o (actually Neek2.0), it also allows you to autoboot games in neek mode directly by selecting it in USBGX interface.
if using sneek or uneek (not "2o") then it will just boot into neek's system menu where you'll have to select the game to launch yourself.
