The demand for a Ventoy-like tool is clearly there, but I hope that one day we'll have an alternative that we can actually trust. Until then it seems that having a small collection of USB sticks is still the way to go, the inconvenience is preferable to the whole installation getting compromised.
I use and recommend ventoy for convenience. It is so convenient. That is, good for nerds to play with hardware and test distros. Not for end users.
For security, I always recommend Burning an ISO into a physical optical disc. Check the ISO MD5 before burning. No thumbdrives.
Then pray god your Government only aproves sales of backdoored hardware where you live. I recommend at least disabling (pulling out) the build-in Network cards (yes, wifi/bt too) and buying usb replacements.
