You can use a prune option to specify the amount of disk space you would like Bitcoin Core to use. This option allows you to keep only the latest block information instead of storing all the data.

1. find your configuration file bitcoin.conf (here you can find the list of possible locations depending on your operating system);
2. set prune parameter to the desired target size in MiB (for example, prune=2048);
3. restart the wallet.
