Beginners • Max # of BLE connections

Hey!
So I have a RPI 4B and it's currently communicating with an IMU via BLE for sensor data that I need to send to the web via mqtts for a project I'm working on.
Based on the research I could find, it seems like there is apparently a max number of connections that the RPI can hold at a time. However, this number seems to keep changing (sometimes it's stated to be 8, 10, or even 24 connections in various forums.)
Does anyone have any insight as to how many connections the RPI ACTUALLY should be able to sustain without any major changes to the firmware? (From my understanding, the cypress CYW43455 ble chip and the available ram on the board are the major limiters of this number)
On top of this, does anyone have any idea of the steps I would need to take to increase the max number of connections from the default? (i'm aiming for upwards of 30 connections but I need AT LEAST 20.) Are there other solutions I should look into? (I've heard about the nrf52840 dongles but I'm not to confident in their range)
