Here's how I fixed my similar issue:

I have Samsung Galaxy A33 5G, with Jio True 5G. Whenever I download a big file say 4/5 GB, the download speed at starting is fast but slowly throttles, and phone heats up. After a while it automatically switches to 4G, which is frustrating.

So I tried removing Back Cover to lose some heat, but that didn't work either.

So, I thought, What if I set my phone to 5G only. But that option was not available on my phone.

After some research I found a app called Net Monster available on Play Store. It has a settings page where you can set your Network Preference to NR only (5G only), and it works like charm, but with some issues, like you can't talk to someone on call. But I fixed that by setting use Power Saving mode that disables 5G and set Network Preference to 4G/Auto, thus I can talk on call. And whenever I need 5G I disable Power Saving mode, thus going into 5G only.

I personally deleted that app after this steps.

Problem Solved! If you are okay to take some pain.

But if the phone really overheats like really it will override the 5G only mode, and set it to 4G/Auto (Its pretty rare scenario). So use it without Back Cover to get maximum benefits.
No worries it will automatically come back to 5G only after phone cools down.

Peace ✌️
