IdentityServer4 authenticate each client separately

I use two different clients. The IdentityServer4 provides API protections and log in form. Can I configure clients to avoid single sign on. I mean that even if I logged in the first client I need to log in the second client too.

My ID4 configuration:

internal static IEnumerable<Client> GetClients(IEnumerable<RegisteredClient> clients)
{
    return clients.Select(x =>
    {
        var scopes = x.AllowedScopes.ToList();
        scopes.Add(IdentityServerConstants.StandardScopes.OpenId);
        scopes.Add(IdentityServerConstants.StandardScopes.Profile);
        scopes.Add(IdentityServerConstants.StandardScopes.OfflineAccess);

        var client = new Client
        {
            ClientId = x.Id,
            ClientName = x.Name,
            AllowedGrantTypes = GrantTypes.Hybrid,

            RequireConsent = false,

            RefreshTokenExpiration = TokenExpiration.Sliding,
            RefreshTokenUsage = TokenUsage.ReUse,

            ClientSecrets = {new Secret(x.Secret.Sha256())},
            RedirectUris = new[] {$"{x.Url}/signin-oidc"},
            PostLogoutRedirectUris = new[] {$"{x.Url}/signout-callback-oidc"},

            UpdateAccessTokenClaimsOnRefresh = true,

            AllowAccessTokensViaBrowser = true,
            AllowedScopes = scopes,
            AllowedCorsOrigins = {x.Url},
            AllowOfflineAccess = true
        };

        return client;
    });
}

All client have the same register code (Maybe it is a problem):

const string oidcScheme = "oidc";
const string coockieScheme = CookieAuthenticationDefaults.AuthenticationScheme;

services.AddAuthentication(options =>
{
    options.DefaultScheme = coockieScheme;
    options.DefaultChallengeScheme = oidcScheme;
})
    .AddCookie(coockieScheme)
    .AddOpenIdConnect(oidcScheme, options =>
    {
        options.SignInScheme = coockieScheme;

        options.Authority = identitySettings.Authority;
        options.RequireHttpsMetadata = false;

        options.ClientId = identitySettings.Id;
        options.ClientSecret = identitySettings.Secret;

        options.ResponseType = "code id_token";

        options.Scope.Add("offline_access");
        foreach (var scope in identitySettings.Scopes)
        {
            options.Scope.Add(scope);
        }

        options.GetClaimsFromUserInfoEndpoint = true;
        options.SaveTokens = true;
    });

any help will be useful.
