You may use (GNOME) Tweaks (aka GNOME Tweak Tool) to do that. First install it (if it is not installed) by running the following command in Terminal
sudo apt install gnome-tweaks
sudo apt install gnome-tweak-tool

Alternatively you may run the following command in Terminal:
gsettings set org.gnome.nautilus.desktop trash-icon-visible false
