Can I possibly hide this?

As a bonus question, what about Amaral@NAZBOX? Can I hide that too?
What do you see there? "Clink"! Disable clink to "hide" it or ask the question to clink's author.
From your screenshot I can make conclusion that you are using cmder. So you questions shall be addressed to the cmder bundle.
If not - you may edit the task {cmd} and strip the CmdInit.cmd call from there.
I'm using ConEmu, not Cmder. Removing CmdInit.cmd didn't help, I even got more "header" information:
Microsoft Windows [Version 10.0.14393]
(c) 2016 Microsoft Corporation. All rights reserved.
I removed the Windows header and the Amaral@NAZBOX by tweaking the CmdInit.cmd file (I created a copy and used my custom version instead).
I just had to remove this cmd /d /c ver | "%windir%\system32\find.exe" "Windows" and this set ConEmuPrompt0=$E[m$E[32m$E]9;8;"USERNAME"$E\@$E]9;8;"COMPUTERNAME"$E\$S. And also change this set ConEmuPrompt1=%ConEmuPrompt0%$E[92m$P$E[90m to set ConEmuPrompt1=$E[92m$P$E[90m.
The clink header though, seems unrelated.
