    Pass the GTK_THEME environment variable to the app:
$ GTK_THEME=<theme> <path>

You can replace <theme> with any available theme:
$ ls /usr/share/themes
Adwaita  Adwaita-dark  Default  Emacs  HighContrast  Pop  Pop-dark  Raleigh

Note that the Adwaita-dark theme is actually Adwaita:dark.
For .desktop files, you need to wrap the command inside a shell command.
For example:
[Desktop Entry]
Version=1.0
Name=PulseUI
Comment=LINUX UI CLIENT
Exec=bash -c "GTK_THEME=Adwaita /opt/pulsesecure/bin/pulseUI"
Icon=/opt/pulsesecure/resource/pulse.png
Terminal=false
Type=Application
Categories=Utility;Application;
StartupWMClass=pulseUI
