How to hide Sim 2 send button in message

[azamalvi4]

I have Samsung Galaxy S10 plus. I have 2 Sims that are running in this phone. I have already setup default Calls and Tex Message to Sim 1. Now issue is that when I type a message then it shows 2 send button for both Sim's and I want to hide/disable Sim 2. Because I mistakenly press sim 2 send button many times and it cost me to send a message. I am unable to sort it out. How can I hide/disable that 2nd sim send button?
