I had a question with battery drain on Dual Sim. I am in Thailand with a 14 Pro. I have a Thai eSIM that is working properly and a US eSIM with Mint Mobile that does not get service. I am noticing that battery is draining due to “No Cell Coverage” presumably from the second US SIM. How do I use both SIMs without this battery drain issue? Is there a specific way to set this up?

The US eSIM with Mint Mobile will continue to search for service as long as it is active. That continuous search for service (Mint) is causing the battery drain. You are in Thailand and Mint Mobile does not provide service there. The best way to avoid the battery drain is to turn that eSIM off when away from a Wi-Fi Network. Turn that eSIM back on when you are connected to a Wi-Fi Network and use Wi-Fi Calling if Mint provides it overseas.

Turn off the unneeded eSIM in Settings>>>Celluar.
You can use Mint over a Wi-Fi Network and use Wi-Fi Calling if Mint provides it overseas. Once you are connected via Wi-Fi then the battery drain should not happen. It only happens when Mint or any carrier keeps searching for service.

Mint does provide wifi calling overseas. So it seems that that I can only use my Mint SIM when I’m on wifi to avoid battery drain. This is a huge limitation from apple, as android phones can easily and clearly toggle each service/feature of each SIM
I want to continue using the US number so I can retain iMessage and receive two factor authentication texts. So turning it off is not an option for me. Can the mint number/SIM use the data on the other Thai SIM to receive texts/iMessage/calls (over 4G or wifi)?
Why would you use the second eSIM that is draining your battery if it cannot get service, because no service is provided there? The issue is with the carrier and not the phone.
Given the fact and reality of the situation, my answer was correct. Whether it was or not helpful, is up to you.

No. But you can keep the Mint number registered on iMessage/Facetime even if you "register" the other (Thai) number. iMessage should prompt you.
Check under Settings>>iMessage to see if the mint number is listed.
I need to use the second SIM for two factor authentication for some of my accounts that only allow US numbers as a their method for two factor authentication.
I also wanted the convenience of my group SMS chats with non-iPhone/iMessage users back in the US to continue seamlessly.
If this is simply a limitation of iOS/iPhone, you could simply state that, instead you chose to respond assuming you knew everything about the context, and did not provide a helpful solution for my question or resolution of my problem.
I asked how to use both eSIMs simultaneously. I know how to turn eSIMs on and off. Your comment is not helpful.
Your "context" was not clear, as you did not state what you specifically wanted to do until prodded further in the thread.
Have a nice day.
