Sync bitcoin-core on deported fullnode ?

[Uld]

I have a good optic fiber internet connection at home and I recentlly decided to run a public fullnode witch bitcoin-core on raspberry-pi.

Since this pc is exposed, I won't put any wallet on it, and I will continue to use my personnal laptop to use my wallet, also with bitcoin-core, in a Debian VM.
My debian VM is rarely up, and my bitoin-core client is always late on the blockchain. I often have to wait many hours for full synchronization.

Is it possible to configure my VM bitcoin-core so it does not use nor download the blockchain and use the fullnode on raspberry-pi instead ?

No, you can't do that. The best you can do is have your wallet only connect to your raspberry pi and only sync off of it. But this won't help with the time required to catch up.

Alternatively you could use Electrum and setup your own Electrum server (full node with some additional things; requires bitcoind) on your raspberry pi. This would let you use your own full node but not have to wait a long time every time you want to use your wallet. However I don't know whether a raspberry pi is capable of running an Electrum server.
