Increasing IMU topic frequency

Hello,

I am using uXRCE-DDS Agent to communicate between cube and companion computer. I am sending IMU data through this agent by subscribing to /fmu/out/sensor_combined ros2 topic.
With this command ros2 topic hz /fmu/out/sensor_combined it tells me I am getting only 100hz.
I have set the serial baud rate 1500000 on the respective TELEM port. Changing this has no effect on the frequency.
Any way to increase this frequency to 200hz?
Also which is the best topic to subscribe to get the accelerometer and gyro data for VIO algorithms?

i also noticed one more thing. When I use PX4 v1.14.4 the frequency of /fmu/out/sensor_combined is slightly less than 200 hz but when I use v1.15.0, the frequncy drops to 100 hz. All the settings/config/params were kept the same while testing both these versions. What could be the reason for this and how to change it since I want to use v1.15.0.
Any help will be appreciated. Thank you
