Minikube start issue on AWS EC2 ubuntu bionic - amazon-ec2

Question

I have got AWS EC2 instance started.
Logged onto the instance using Putty client.
Below all commands I tried on EC2 instance which is Ubuntu 18.04.
Configuration details of EC2 are as follows
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Codename: bionic
I have installed docker and virtualbox
~$ docker --version
Docker version 19.03.8, build afacb8b7f0
$ dpkg -l | grep 'virtualbox'
ii virtualbox-5.2 5.2.30-130521~Ubuntu~bionic amd64 Oracle VM VirtualBox
$ lscpu | grep Virtualization
Virtualization type: full
I tried to start minikube.
$ minikube start

I went to all those jira specified in error log but of no use. Most of those doesn't talk about issue within Amazon EC2 ubuntu 18.04 .
Questions:
how do I enable VT-X/AMD-v in BIOS in logged in EC2 instance which is ubuntu 18.04? Is there any command I can try? note: I don't have access to go to AWS EC2 instance GUI.
is AWS EC2 Ubuntu 18 instance compatible with virtualbox 5 or 6 to start minikube ?

Questions: how do I enable VT-X/AMD-v in BIOS in logged in EC2 instance which is ubuntu 18.04? Is there any command I can try? note: I don't have access to go to AWS EC2 instance GUI.
You don't, EC2 is a virtual server and You have no access to the BIOS.
To use Minikube on EC2 you need to start it without vm driver so just execute $ minikube start --vm-driver=none. This is described here if you insist on using Minikube.
Instead of installing Minikube I would recommend using kubeadm and setting single control-plane cluster with kubeadm.
