Why does visadev call continuously viRead?

Hi,
after connecting to the instrument using:
dso=visadev('TCPIP0::10.136.236.197::inst0::INSTR');
the conncetion is correctly created but Matlab starts to send continuosuly viRead messages to the instrument as visible using the VisaMonitor:

On the other hand, if I open the connection to the same instrument using the old command ;
dso = visa('keysight','TCPIP0::10.136.236.197::inst0::INSTR');
fopen(dso);
there is no issue...the viRead commands are not present anymore:

Any idea about how to suppress those continuous viRead messages when visadev is called?
Thank you.

I had the same issue with visadev & keysight instruments using r2021b, upgrading to r2022a solves this issue.
