How to delete scheduled task from command line without confirmation? (schtasks delete)

Question

I can create a task from command line like this:

schtasks /create /tn SomeTask /tr "do.bat arg1 arg2" /sc ONCE /st 00:00:00 /sd 01/01/1991 

and now I need to delete it. However the command needs to be confirmed and I don't know how to do that from BATCH file (bat/cmd).

C:\> schtasks /delete /tn ContextSwitchTask WARNING: Are you sure you want to remove the task "ContextSwitchTask" (Y/N)? C:\> echo Y | schtasks /delete /tn ContextSwitchTask WARNING: Are you sure you want to remove the task "ContextSwitchTask" (Y/N)? Y ERROR: Invalid input. Type "SCHTASKS /DELETE /?" for usage.
