How can i improve build pipeline performance azure devOps MSHostedAgent?

I have created a build pipeline for my angular and web api. It has 3 jobs. However every time it does npm install and dotnet.exe. Do we need this every time or can we cache this. If we can cache this how can I add this cache step? Below is my yaml script:

variables:
- name: solution
  value: 'MyProject.sln'
- name: buildPlatform
  value: 'Any CPU'
- name: buildConfiguration
  value: 'Release'
stages:
- stage: StartAzVMAgent
  jobs:
  - job: MsHostedAgentJobStartAzVM
    timeoutInMinutes: 0
    pool:
      vmImage: 'windows-latest'
    steps:
    - task: AzureCLI@2
      displayName: Azure CLI
      inputs:
        azureSubscription: "Az-DevOps-AgentManager"
        scriptType: ps
        scriptLocation: inlineScript
        inlineScript: |
          az --version
          az account show
          az vm start --name  Deployment-Agent --no-wait --resource-group Rg_Deployment
