Configure SNMP on ubuntu 20.04

I need to monitor a system via SNMP and integrate it with zabbix 5.0. I was making some test on my local machine so I installed snmp, snmpd and snmp-mib-downloader on ubuntu 20.04. I need to monitor all these variables: variables to monitor via snmp

The problem is that when I try to see some of those variables on my local machine, this happens:

snmpwalk -v 2c -c public 127.0.0.1 DISMAN-EVENT-MIB::mteHotTrigger.0

And I get:

DISMAN-EVENT-MIB::mteHotTrigger.0 = No Such Object available on this agent at this OID

Is there a way to change the value of the values of the trigger? Why is it that I cannot see the value of some of those variables?

The DISMAN-EVENT-MIB defines the MAX-ACCESS for mteHotTrigger as accessible-for-notify.

From the SNMPv2-SMI:

The value "accessible-for-notify" indicates an object which is accessible only via a notification (e.g., snmpTrapOID [5]).

In other words, this particular value cannot be retrieved using any kind of GET request (in fact, if you read the description of that variable, it only makes sense in the context of a notification). You need to set up your local machine to receive SNMP traps (notifications), and configure your managed machine to send traps to it.
