We cannot answer this question for your.

You already realized that you are trading speed for security when you
switch off the checksum verification.

It depends on your use case and your project's requirements if this
acceptable or not.  If you're building a consumer grade MP3 player
or a TV remote control, then it's probably fine.  If you build a
distress call system or a remote control for medical equipment the
technical requirements may be very similar, but your evaluation of the
speed vs. risk question may come to totally different results.

Best regards,

Wolfgang Denk
