Hi @Oleg Tserkovnyuk ,
According to my research and testing, it is currently not possible to get the Site storage limits and Default time zone in the global setting by using PowerShell. As you said, currently we can only use the PowerShell to set specific site storage limits, and change special site time zone.
I suggest you mention a feedback on this issue. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding.
