What happens if I disable bits?

Excuse me, I'm curious about something related to cryptocurrency transactions. I've come across the term 'bits' in the context of transactions, and I'm wondering what would happen if I were to disable them. Would disabling bits affect the speed or cost of my transactions in any way? Could it potentially impact the security of my funds? Are there any other implications I should be aware of before making such a change? I'd appreciate any insights you could provide on this matter.
