Difficulty Enabling DRI3 on Debian (bullseye)

I'm having difficulty enabling DRI3 in Debian bullseye. I added the following to my /usr/share/X11/xorg.conf.d/20-intel.conf. I'm using integrated Intel graphics on an Intel i5-6200U (4) @ 2.800GHz with Intel Skylake GT2 [HD Graphics 520].

~ > cat /usr/share/X11/xorg.conf.d/20-intel.conf 
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "AccelMethod"  "sna"
    Option      "TearFree"     "true"
    Option      "DRI"          "3"
EndSection

When I run xdpyinfo, I get the following

 ~ > xdpyinfo | grep -i "DRI"
    DRI2
    DRI3

which seems like good news, but when I check the log file, I get

 ~ > cat /var/log/Xorg.0.log | grep DRI
[     6.333] (II) intel(0): [DRI2] Setup complete
[     6.333] (II) intel(0): [DRI2]   DRI driver: i965
[     6.333] (II) intel(0): [DRI2]   VDPAU driver: va_gl
[     6.333] (II) intel(0): direct rendering: DRI2 enabled
[     6.340] (II) Initializing extension DRI3
[     6.375] (II) GLX: Initialized DRI2 GL provider for screen 0
[     6.376] (II) Initializing extension XFree86-DRI
[     6.376] (II) Initializing extension DRI2

which suggests that DRI3 is not enabled. How should I go about fixing this?
