Is it possible to use the same OS image across VPS providers?

I bought several VPSes across different VPS providers. Although I
chose Ubuntu 20.04 on all providers, I found they use different Linux
kernels. There might be other differences as well. In order to keep my
running environment stable, I want to use the same OS image in all
VPSes. But I think it's impossible, it seems, that every vendor has
some modification on internet options at least.

Rent dedicated servers instead if you want full control.

If they're VMs, just install the kernel you want - keeping them
updated is your responsibility anyways. If they're containers
(Virtuozzo), you're not gonna change the kernel anyways.

You can export VM's and move them from provider to provider like that.
How about switching everything to containers instead so the host OS
does not matter?

It shouldn't be a problem.

Some VPS will manage your kernel for you and use a 'optimized' kernel.
You can often change it to what you want.  But sometimes you have to
go into the control panel to change it.
