You can use BreakRoleInheritance method of ListItemAllFields property. In my code snippet "Test Library" is the document library title and "Test Folder" the name of the target subfolder.

using (var scope = host.Services.CreateScope()) 
{
    // Ask an IPnPContextFactory from the host
    var pnpContextFactory = scope.ServiceProvider.GetRequiredService<IPnPContextFactory>();

    // Create a PnPContext
    using (var context = await pnpContextFactory.CreateAsync(new Uri(siteUrl)))
    {
        // Get Root Folder
        var rootFolder = (await context.Web.Lists.GetByTitleAsync("Test Library", p => p.RootFolder)).RootFolder;

        // Ensure SubFolder
        var subFolder = await rootFolder.EnsureFolderAsync("TestFolder");

        // Break Inheritance on SubFolder [BreakRoleInheritance(bool copyRoleAssignments, bool clearSubscopes)]
        subFolder.ListItemAllFields.BreakRoleInheritance(false, true);

        // Get current user
        var currentUser = await context.Web.GetCurrentUserAsync();

        // Find role definition
        var roleDefinitions = (await context.Web.GetAsync(p => p.RoleDefinitions)).RoleDefinitions;
        var editRole = roleDefinitions.AsRequested().FirstOrDefault(p => p.Name == "Edit");

        // Add role to selected user
        await subFolder.ListItemAllFields.AddRoleDefinitionAsync(currentUser.Id, editRole);
    }
}
