How to switch power save mode between PS Poll and UAPSD (WMM) modes in CLI?

I'm trying to figure out if there are any chances to switch on/off U-APSD power save mode at my laptop. Currently I found a command to switch power save mode on/off: root@host # iw dev wlan3 set power_save on/off I suppose it just switches power save on/off without consideration of PSPoll/UAPSD power saving mode. So, I guess if AP supports UAPSD it will be used. But I need UAPSD (WMM) to be off. Also I saw a WMM is availabe for my card: root@host # iw dev wlan3 station dump Station 00:e1:6d:XX:XX:XX (on wlan3) inactive time: 148 ms rx bytes: 5983752 rx packets: 27939 tx bytes: 1075591 tx packets: 8168 tx retries: 632 tx failed: 0 signal: -58 dBm signal avg: -56 dBm tx bitrate: 130.0 MBit/s MCS 15 authorized: yes authenticated: yes preamble: long WMM/WME: yes MFP: no TDLS peer: no So is there any possibility to switch WMM on/off?
