The profile file should look:

function IsVirtualTerminalProcessingEnabled {
	$MethodDefinitions = @'
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr GetStdHandle(int nStdHandle);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern bool GetConsoleMode(IntPtr hConsoleHandle, out uint lpMode);
'@
	$Kernel32 = Add-Type -MemberDefinition $MethodDefinitions -Name 'Kernel32' -Namespace 'Win32' -PassThru
	$hConsoleHandle = $Kernel32::GetStdHandle(-11) # STD_OUTPUT_HANDLE
	$mode = 0
	$Kernel32::GetConsoleMode($hConsoleHandle, [ref]$mode) >$null
	if ($mode -band 0x0004) { # 0x0004 ENABLE_VIRTUAL_TERMINAL_PROCESSING
		return $true
	}
	return $false
}

function CanUsePredictionSource {
	return (! [System.Console]::IsOutputRedirected) -and (IsVirtualTerminalProcessingEnabled)
}

if (CanUsePredictionSource){ 
  Import-Module -Name Terminal-Icons
  Import-Module PSReadLine
  Set-PSReadLineOption -PredictionViewStyle ListView -PredictionSource History -HistoryNoDuplicates
}
