Browsing with encrypted libraries : Increase the cache duration of the password in memory?

I have a question about the browsing with encrypted libraries.

I have read in the “Security Questions” of the that “When you are browsing encrypted libraries via the web browser or the cloud file explorer, you need to input the password and the server is going to use the password to decrypt the “file key” for the library (see description below) and cache the password in memory for one hour.

Is it possible to increase this duration on the server for it be more than 1 hour ? 2 or 4 for exemple.

Thanks a lot in advance!
