Hi! I use a password with all numbers, and in every startup the "caps lock" for the number keyboard is always off, how can i enable from start this feature?
Hello and welcome to the forum.
Check your EFI/BIOS.
There should be a settings for numeric keys ON/OFF at the start up.
Hi! I have a Dell Optiplex and i cant find this options in the BIOS 
Which model?
Do you have the latest version of BIOS?
dario-OptiPlex-9010
Looks like the latest BIOS is O9010A30.

Also, If using Zorin Lite (XFCE):
sudo apt install numlockx
sudo nano /etc/lightdm/lightdm.conf.d/lightdm.conf
Add this line: greeter-setup-script=/usr/bin/numlockx on and save and exit.
Install numlockx on Zorin Core (Gnome):
sudo apt install numlockx
Navigate to ~.profle and add these lines to it:
if [ -x /usr/bin/numlockx ]; then
/usr/bin/numlockx on
fi
Save and exit, log out and in to test. (Or reboot).

I try this but it does not work for me 
Sorry, I do not use Gnome D.E. so, I am no expert.
try:
su gdm -s /bin/bash
gsettings set org.gnome.settings-daemon.peripherals.keyboard numlock-state on
Hi! No problem, im not an expert nethier. Your last message also dont work, it not found "gdm" command.
Try just the gsettings option - What I am using may be too outdated for gnome 3.38...
gsettings set org.gnome.settings-daemon.peripherals.keyboard numlock-state on
