You don't have to.
You could use Neutrino or SPV sync or even trustedcoin plugin by fiatjaf

This.
Also, if you already have downloaded the whole blockchain and are spinning up another node for whatever reason, you can just strait copy the blockchain files from one node to the other.

Mid-term
Ln node

For a LN node, especially if is a public node, is better to have full sync.
But if you run it on a limited machine, you could use those mentioned methods. LN only needs to link to a source of blocks to verify and sync the graph and txs. Nothing else.
Also if you have a private LN node, you don't really need to run a full BTC node and a LN node.
Check my guides about private LN nodes:

Good
So i can self custody without downloading hundred of Gbs

exactly.
I wrote several guides about these scenarios on my substack (over 60). Please take your time and read them.
I am not saying that running a full node is not good, but contrary. But also depends in which situation. Not always you need to run a full node.
