Unable to turn off MIUI optimization for MI 9

Hi, I need to turn off MIUI optimization for installing apks using "Split APKs Installer (SAI)", apparently this feature is hidden in developer options, I'm using 20.1.21 | Beta xiaomi.eu rom, Is there are any other way to turn off temporary this setting? tried with "setprop persist.sys.miui_optimization false" but no luck
Thanks in advance
