Thank you for suggestion, we'll consider changing the default UUID provider to use UUIDv7 in the next feature release.

Currently you can use a custom provider for attributes annotated with @JmixGeneratedValue if you define an appropriate EntityInitializer bean in your project, for example:

package com.company.onboarding;

import io.jmix.core.EntityInitializer;
import io.jmix.core.JmixOrder;
import io.jmix.core.Metadata;
import io.jmix.core.UuidProvider;
import io.jmix.core.entity.EntityValues;
import io.jmix.core.entity.annotation.JmixGeneratedValue;
import io.jmix.core.metamodel.model.MetaClass;
import org.springframework.core.Ordered;
import org.springframework.stereotype.Component;

import java.util.UUID;

@Component
public class MyGeneratedIdEntityInitializer implements EntityInitializer, Ordered {

    private final Metadata metadata;

    public MyGeneratedIdEntityInitializer(Metadata metadata) {
        this.metadata = metadata;
    }

    @Override
    public void initEntity(Object entity) {
        MetaClass metaClass = metadata.getClass(entity);
        metaClass.getProperties().stream()
                .filter(property -> property.getRange().isDatatype()
                        && property.getRange().asDatatype().getJavaClass().equals(UUID.class)
                        && property.getAnnotations().get(JmixGeneratedValue.class.getName()) != null)
                .forEach(property -> {
                    if (EntityValues.getValue(entity, property.getName()) == null) {
                        UUID uuid = UuidProvider.createUuid(); // use your UUID provider
                        EntityValues.setValue(entity, property.getName(), uuid);
                    }
                });
    }

    @Override
    public int getOrder() {
        return JmixOrder.HIGHEST_PRECEDENCE - 10;
    }
}

Pay attention to the order - it must be a lower number (higher precedence) than defined in the GeneratedIdEntityInitializer bean of the framework.

I found a good implementation of various UUID versions and made a small test of ordering of different types of UUIDv7.
Add uuid7 and test (WIP)
